Android native coverage report regression

[mikehardy]

Noticed that android native coverage regressed here while working through a similar-but-different problem in AnkiDroid

I think the problem here will be related to the firebase performance plugin though as indicated in this issue, needs confirmation: firebase/firebase-android-sdk#5456

(problem in AnkiDroid was a shared test code dependency between unit and android not working, but when I checked coverage here I noticed it was also zero...)

I was quietly working on this one low-priority before the rest of the Invertase team swarmed into RNFB and started kicking ___ and taking names 😆 so hadn't updated status

I looked into this more and I think we do have coverage still on android, and it's inconclusive exactly what caused the regression and/or if it's still happening. I've got this one picked apart on a branch and was testing combinations, but don't have a final thing to point at yet
