Fix tests

[fmasa]

PR tests were previously failing because there are currently two tests that both initialize the default Firebase app.

I originally wanted to just use different instance per each test, but FirebaseApp internals always expect that default app exist, so I added a simple cleanup before each test instead.

@nbransby The scacap/action-surefire-report GH action does not play well with PRs opened from forks. Should I try to fix it, or do we drop it altogether? 🤔

Are we using something else for the firebase-kotlin-sdk?

[fmasa]

@nbransby For firebase-kotlin-sdk the test output is only attached to a Job when test failed..

But that is only for other targets. There is no CI running for JVM builds in firebase-kotlin-sdk 🤔

we can do the same here if thats easiest

Yeah we probably should add that sometime!

@nbransby I dropped the problematic action. Didn't get to this sooner. :slightly_smiling_face:
