Unrecoverable state if test discovery errors out

[hoylemd]

Your environment

• vscode-ruby-test-adapter version: v 0.9.1
• Ruby version: v2.7.5
• VS Code version: 1.70.2 (Universal)
• Operating System: Darwin arm64 20.6.0 (Macos 11.5.2 Bug Sur)
• RSpec or Minitest version: rspec 3.10

Expected behavior

If test discovery fails, for there to be some way to retry after fixing the problem (i.e. make the reload button work?)

Actual behavior

If the test discovery command fails, The testing sidebar remins in a state where it looks like it's looking for tests, but it will never complete. The 'reload' button is still spinning, and clicking it does nothing. The best workaround I've found is to disable the extension (requiring VSCode to reload) fix the problem, and then re-enable it. Because the test suite in my project depends on some port-forwarding being set up, and I run that forwarding in a terminal in VSCode, I get into this irrecoverable state every time I open VSCode after a reboot.
