[Login] Handle correctly M_LIMIT_EXCEEDED error code

[giomfo]

This error should be received when the user fails to login more than three times.

Currently the login screen is frozen with a loading wheel when the user fails 3 times to provide the correct password (NOK)

The login should not be blocked, and the application must display a specific message:
"Vos trois dernières tentatives de connexion ont échoué. Veuillez réessayer dans 30 minutes"

I just observed this error message already exist in the code v2 (see login_error_limit_exceeded string). The bug may be on the handling of this error... This error is not expected from matrix.org, so I don't think you can reproduce the issue with Element-Android, except if you test to login with a Tchap account

@Florian14 can you please port the fix you did on Elment-Android?
