Adding and stopping transceiver before first offer will result in unremovable transceiver

[mickel8]

To remove stopped transceiver it has to be associated with an mline. This means that adding and stopping transceiver before the first offer will result in unremovable transceiver. This transceiver cannot be reused using addTrack or by changing the direction, see fiddle: https://jsfiddle.net/5tweyjL6/4/

Surprisingly we have an issue for that already: #2838
