Refine UI output when "Add a new project" takes a long time

[koppor]

I try to add a project, then I get the spinner:

The text reads "Verify valid Git repository in selected folder before importing". I think, that should be "Verifying valid Git repository in selected folder before importing.", because the operation is ongoing (and not going to happen)

The console output is

2024-03-22T08:33:56.261249Z  INFO list_projects: gitbutler-app/src/projects/commands.rs:132: close time.busy=10.7µs time.idle=30.3µs

When I tried the Linux repository (#3512), it also took a long time, seemingly because gravatar image were eagerly loaded for all of the 30k unique authors.
Is the project you were using for testing public, so that I could try it as well? Thank you.

Yes, the project is public and available at https://github.com/jabref/jabref/.

Thanks for helping!

I think the issue here was that there were internal failures that weren't communicated very well. When trying this now, the program fails with a popup saying that repositories with submodules aren't supported.

Thus, I am closing this issue as fixed, but please feel free to keep commenting or to reopen in case I am missing something.
