[Change Request] - All failures during automatic linking should be considered

[MrAsterisco]

Is your feature request related to a problem? Please describe.
With #14 , we introduced the concept of automatic linking that fails and allows clients to determine whether they want us to restore an anonymous user automatically. This is currently being done only for invalidCredentials and not for all errors. This is also being executed in all cases of invalidCredentials and not only when an automatic link has been performed.

Describe the solution you'd like
When automatic linking is required, we should intercept any error from Firebase and map it to the new behavior introduced in #14 .
