At startup and after resetting the playlist, loading the song list and
preloading the first song started at the same time. When the list
answered last, it cleared the playlist and dropped the preloaded song.
Preloading now starts once the list has loaded, and loading the list is
retried if it fails.
The previous tests never compiled: they used GUT's assert functions,
Godot 3 APIs and reassigned autoload functions, so no test ran.
- 90 tests: unit tests for the playlist, songs, player scoring, time
formatting, search and the server client, plus integration tests
that run MainWindow and SyncWindow against a fake server
- Keybind tests check that Alt+<number> and Ctrl+Alt+<number> keep
following the player rows while players are added and removed
- run_tests.sh finds Godot and runs the suite headless (~10 seconds)
- CI runs the tests before the build job in gitea-build.yaml; the
separate test.yml used a GitHub action that does not exist
- GdUnit4 is committed instead of ignored, since the project enables
it, and .gitea/ is no longer ignored
- Exported builds leave out tests/ and addons/gdUnit4/
