Login Email should be case insensitive
### Expected Behavior
You should ignore the case of the email when logging in. I could not log in and couldn't work out why. Turns out the autocorrect that I have running that changes chekrite to ChekRite was causing this issue. Email addresses are case insensitive.
### Current Behavior
Case sensitive emails prevent you from logging in when you change the case slightly from what you registered.
### Possible Solution
Ignore case for login credentials (but obviously not passwords)
### Steps to Reproduce
Try to login with a known email address and password however change the case of one or two characters in the email.
### Context (Environment)
Prevents users from logging in if they are not aware of this defect.
