tests/notify: Always print the diagnostic messages

We're using the TAP mode of GTest, so we can always emit diagnostic
messages using g_test_message(), without necessarily caring about
verbosity.

-## GTK CI infrastructure
-
-GTK uses different CI images depending on platform and jobs.
-
-The CI images are Docker containers, generated either using `docker` or
-`podman`, and pushed to the GitLab [container registry][registry].
-
-Each Docker image has a tag composed of two parts:
-
- - `${image}`: the base image for a given platform, like "fedora" or
-   "debian-stable"
- - `${number}`: an incremental version number, or `latest`
-
-See the [container registry][registry] for the available images for each
-branch, as well as their available versions.
-
-Note that using `latest` as version number will overwrite the most
-recently uploaded image in the registry.
-
-### Checklist for Updating a CI image
-
- - [ ] Update the `${image}.Dockerfile` file with the dependencies
- - [ ] Run `./run-docker.sh build --base ${image} --version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --version ${number}`
-   once the Docker image is built; you may need to log in by using
-   `docker login` or `podman login`
- - [ ] Update the `image` keys in the `.gitlab-ci.yml` file with the new
-   image tag
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new CI image
-
- - [ ] Write a new `${image}.Dockerfile` with the instructions to set up
-   a build environment
- - [ ] Add the `pip3 install meson` incantation
- - [ ] Run `./run-docker.sh build --base ${image} --version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --version ${number}`
- - [ ] Add the new job to `.gitlab-ci.yml` referencing the image
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new dependency to a CI image
-
-Our images are layered, and the base (called fedora-base) contains
-all the rpm payload. Therefore, adding a new dependency is a 2-step
-process:
-
- 1. [ ] Build and upload fedora-base:$version+1
- 1. [ ] Build and upload fedora:$version+1 based on fedora-base:version+1

+/* Change Display

+ * displays is that they can be on a completely separate
+ * computers, as long as there is a network connection to the
+ * computer where the application is running.
+ *
+ * Only some of the windowing systems where GTK runs have the
+ * concept of multiple displays. (The X Window System is the
+ * main example.) Other windowing systems can only handle one
+ * keyboard and mouse, and combine all monitors into
+ * a single display.
+ *
+ * This is a moderately complex example, and demonstrates:
+ *
+ *  - Tracking the currently open displays
+ *
+ *  - Changing the display for a window
+ *
+ *  - Letting the user choose a window by clicking on it
+ *
+ *  - Using GtkListStore and GtkTreeView
