Fix Out of Bounds error during testing.

[JoeZiminski]

Often in testing we were getting errors like:

FAILED test_tui_create_folders.py::TestTuiCreateFolders::test_create_folders_formatted_names - textual.pilot.OutOfBounds: Target offset is outside of currently-visible screen region.

This is due to the screen not being large enough, as discussed here. They provided the very useful information that there is a function app.save_screenshot() that allows you to see the state of the screen at the test time.

It turned out at the issue (in this case) was that when clicking onto the project selector screen, it was completely blank. This led the terminal size of shrink and nothing was clicked on when the app tried to click on the project name.

The issue was that I forgot to add pilot.pause() after the call to click on the project selector screen

 await pilot.click("#mainwindow_existing_project_button")

so the test was moving directly onto the next step (clicking the project button) before the screen had loaded.

[EDIT]

Also, this fixed a case I found where forgot to add assert to a check. It was just easier to include on this PR.

Hey @niksirbi tests are failing because all PRs tests are failing in different ways 😆 we can merge this one next and I'll rebase the other PRs onto main and hopefully the situation will be resolved!

[JoeZiminski]

actually scratch that, I saw you approved the others cheers! we can just merge them all and things should be fixed

Nice job hunting down this one, and a very satisfying 1-line fix.
