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.
