[PATCH obexd] phonebook-tracker.c: Calls query speed-up

[Slawomir Bochenski <lkslawek@gmail.com>]

Another change regarding performance of call history queries. This makes
them non-sensitive (in terms of speed) to the corner case situations when
there are hundreds of contacts all having the same phone number.
