Also look up number as an "Internet call" address.

If a number in the call log is not found as the number of a contact,
also check whether the number was added as part of an "Internet call"
address for one of the contacts.

Normally, one should put a full SIP address in the "Internet call"
address, but it is possible to put just a plain phone number and that
still correcly works to dial that number using the internet calling
feature.

However, the call log does not correctly match the number in that case,
because a plain phone number is never looked up as an "Internet call"
address.

This commit adds that look-up, if the regular look-up of a phone number
fails.
