Subject: -Fixed a crash while recreating CreateKeyEmailFragment -Email data is
 properly restored while rotating the Activity. -Added necessary logic to
 guarantee that an email is actually valid before continuing, there are
 verifications for empty, duplicated and invalid formatted emails for both
 additional and main email.
