Performance issues with BasicAuth and LoginAttempts

Browse Source 
Two functions interact with the LoginAttempt object which when used in conjunction with BasicAuth result in significant performance degradation over time, as the LoginAttempts Table fills.

This fix adds an index to the lookup column EmailHashed and removes the Email filter part of getByEmail() so it can use the index resulting in a much faster query.
