Title: Bugfix for previous pullrequest "Duplicate e-mail addresses: U4-315, U4-...

...2147, U4-304"

There was a bug in the previous pullrequest that didn't allow a member
to saved if the email wasn't changed. Furthermore duplicate emails are
now prevented if requireUniqueEmail was false, but is switched to true
(when saving a member)
