Fix error generation when status is .internal

Description

Expectation When an internal error is received on the client side (iOS), I would expect to contain the following:

code: internal
message: <some string>

Reality What actually happens is that the message is dropped/rewritten with INTERNAL, so any potential critical information gets destroyed.

Reproducing the issue

From a cloud function throw the following error:

throw new functions.https.HttpsError('internal', 'Something really bad happened!')

On the client, the content of the generated message is:

code: INTERNAL
message: INTERNAL
