User can not change availability because its out of event timeframe

[s-light]

Expected Behavior

Allow Orga to change event timeframe without getting users stuck

Current Behavior

If event timeframe is shortend and user had availability times set
he is not able to edit anything in his profile -as in this the old time is stored (but not shown)
and so triggers an The submitted availability is not within the event timeframe.validity error.

Steps to Reproduce

1. Setup an event for two days
2. user → submit talk and set your availability to all day for both days
3. change event timeframe to one day only
4. user can't change his availability or any other profile thing anymore.
5. also he can't confirm submissions - seems to be similar bug. (but no error message)

Context

Arguably, availability not within the event time frame should just be discarded in all availability forms, instead of raising an error.

found yesterday: same bug happens for rooms too....

Availability forms are the same everyhwere, so seeing the same issue here is expected. Thanks for mentioning it, though, so we'll have another place to test the fix :)
