Pre Member should have a email

[agmes4]

Bug

when trying to add a pre member for testing purposes I encountered a bug in which I just got a 500 when request the membership request. This happend cause I did not set a mail address. Its in schema defined that a pre member does not need a email.
I think this is counter intuitive.

fix

I see two options in order for it to make more sense

• remove the is nullable
• remove the check in the request /user/json/member-requests

I think we should require the email for PreMembers.
For this we need to overwrite the email Column for PreMembers
