Philipp Hörist 16fd64873e Add new logger methods 
Goal is to make the logger module easier to maintain in the future

- extract deduplication out into a own method, so we can use it
on its own in some other places.

- add new insert_into_logs() method
the DB fields we want to write to are passed as arguments, this makes
it so we dont have to change the method when we add or remove DB fields
in the future.

- instead of using get_jid_id() all around gajim to get the jid_id
before we write to the DB, we only have to pass the jid to
insert_into_logs(), it makes sure to get the correct jid_id or add
one in case it doesnt exist.
