EQM: Only show save success message when saving

[nucleogenesis]

Summary

Only shows the "Changes saved successfully" message when actually saving the quiz.

There are now no longer any snackbars when the user does a few things, like selecting resources or applying their new section settings, perhaps we'll want to improve on this in the next iteration.

References

Fixes #12333

Reviewer guidance

Try to save and to save & close both in the "Select quiz" and throughout the quiz creation flow - you should only see a "Changes saved successfully" message when you've saved the quiz successfully.

Hi @nucleogenesis here are the issues I was able to identify after this change:

1. We need a success message after clicking the "Apply settings" button because otherwise it seems that nothing has happened:

2024-07-02_15-23-36.mp4

2. We need a success message after having added additional questions:

adding.questions.mp4

3. (Probably a known issue or a follow-up) - When I attempt to save the quiz without a title and then add a valid title, the text 'There was a problem saving the quiz' remains displayed which makes the user wonder whether the quiz is saved:

save.mp4

4. (Probably a known issue or a follow-up) - I am getting an error in the console when I attempt to delete a section by first clicking the Options button and then selecting 'Delete section':

delete.the.only.available.section.mp4

Thanks @pcenov !

For (1) and (2), this was discussed a bit on Slack today and @marcellamaki noted that now, where there are no snackbars as you noted there, the user does see a sort of "confirmation" in that the side panel closes. This should happen for all cases. We'll gather some feedback from the team around this area.

For (3) I actually fixed it last night in a different body of work, but didn't include it because I wanted to be sure it wasn't a bug already reported. It has not been reported elsewhere, so I've committed here.

For (4) the best solution I could come up with here to mitigate the issue is to make the larger error box dismissible. I initially was going to make it so that typing into the title box dismisses the larger error box, but that might not be desirable in some cases. In this case, however, the user can dismiss it so I hope this is a suitable UX.

thanks for making these last handful of adjustments, @nucleogenesis!
