chore: remove unused file

[DoctorJohn]

Description

I always stumble across this file that I believe was commited by mistake since it does not contain real test, does not run as part of the test suite and is not referenced anywhere.

Test Plan

• Tests still pass
• Checked that file is not referenced anywhere

I'm sure it hasn't been included by mistake, it's just currently unused.
Seems we have to add this to our tsconfig for type tests during compilation.
See: https://github.com/invertase/react-native-firebase/blob/c2c457608c865f6d25e4b9b6689cbc00721de194/tsconfig.json#L2C3-L2C69
