Rework report viewer error handling

[Kr0nox]

This PR reworks the error handling of the report viewer.

Rewrite Error View:

• Not takes a more detailed message about the error
• Can redirect to different pages

Error handling:

• On Error redirect to Error view which offers to go back to closest possible view
  • Error on Overview => File upload
  • All other views => Back to Overview
  • Errors on the error view get alerted to prevent an infinite error loop
• Error on File upload page:
  • Get displayed under the upload menu
• Error on routing:
  • Try to get to Error View
  • If not possible alert error
• All errors that propagate to the root get alerted

Where we catch errors:

• On parsing and reading files
• In the setup function over the build in livecycle hook onErrorCaptured
• On routing
• In the root of the App

Funny test case, that completely crashed the report viewer: If you drag a completely unrelated zip (i tested this with a zip containing the JPlag font, don't ask why 😅) this leads to a frozen viewer with the message Loading Files.... The console prompts the error of a missing overview file, but the UI does not reflect this not-to-resolve problem 😁

Edit: Of course, this does not happen in this PR, but in previous versions. Should have mentioned that.

Missing error: Arbitrary router errors, e.g., manually navigating to http://localhost:8080/asdf

Opening up the report viewer greets me with a red For more details check the console. - Is this intended? If yes, why?

Missing error: Arbitrary router errors

Should be implemented now

Opening up the report viewer greets me with a red For more details check the console.

This, was due to the FileUploadView#L40 having an == 0 instead of an > 0

I could not reproduce it with a zip. Although I could with other file types. It should be fixed now (Errors not shown due to same comparison error as above and not resetting the loadingFiles varriable). Can you confirm that again with you zip? @sebinside
