Fail file-transfer if proxy session of candidate does not exist
Test-Information: Tested with a buggy XMPP client that calculates S5B DSTADDR in a non-standard way. Previously this lead to Swift crashing on an assert. Now Swift just indicates file-transfer failure to the other party. Change-Id: I4ed47f9647a1851f2a5101657bcd569c106d638f
