refactor: split EmailHandler in 3

InvalidEmailHandler - handle emails with an invalid format
LocalEmailHandler   - handle emails on the local domain
EmailHandler        - handle all other emails by using hkp

This is a preparation to add leap provider email lookup and remove
hkp eventually. But for now we keep the behaviour the same and only
refactor.
