* Do not request media sections for transceivers that cannot send

getNumUnmatchedTransceivers counted every local transceiver without a mid.
A transceiver whose track was removed before its section was negotiated
(direction recvonly, no sender) or that was stopped (inactive) can never be
matched to the recvonly section the remote adds in response to a
MediaSectionsRequirement, so it stayed "outstanding" forever: every answer
asked the remote for a section for it again, the remote appended another
batch of transceivers each round, and its offer grew by a fixed amount per
negotiation until it exceeded limit.signal_message_size_limit and the
signalling connection was closed (full reconnect, then the cycle restarts).

Count only transceivers that have something to send. A released transceiver
that AddTrack reuses later becomes sendrecv and is counted again.

* Address review: blank lines between test functions, assert transceiver reuse
