Set answer as sendonly in case of a recvonly offer

Browse Source 
When a local peer connection has a single transceiver with a sendrecv
direction, and the remote has a transceiver with a recvonly direction,
the local peer connection must change the transceiver direction to
sendonly.

When a local peer connection has a single transceiver with a recvonly
direction, and the remote has a transceiver with a recvonly direction,
the local peer connection must create another transceiver with a
sendonly direction.

A unit test is added to cover all possible cases.
