fix: make it impossible to overwrite default key

Browse Source 
Replacing default key
when a profile is already part of
verified groups results in
`[The message was sent with non-verified encryption. See 'Info' for more details]`
messages for other users.

It is still possible
to import the default key before
Delta Chat generates the key.
