ui: Adds better error passthrough, disable/unauthorize properly on error (#5041)

1. Ensure any unexpected developer errors are passed through/shown
2. Previously when errors where returns/resolved the special
isEnabled/isAuthorized would never get resolved. This was fine as they
were set to false to start with anyway, but this resolves them again to
false for completeness
3. Improved unit testing coverage
