It should be fine to have 1 and 2 together, it is less troublesome if
somebody is using git blame to check the history.

It is possible that phonebook_pull_read is invoked several times
submitting multiple pull requests without closing PBAP object. E.g. when
maxlistcount value is small and size of call history is large enough.
The result is possibility of different data structures (gstring and
contact_data) to be mixed in a single GSlist that may lead to undefined
behaviour.
