Baking transforms multiple times on the same object results in multiple transform tracks

When baking we only look for the first transform track to mute, so if there are more than one, only one will be muted.

1. Create a sequence and add an object to it with a transform track
2. Select the object binding and bake transforms multiple times from the sequence Actions menu

RESULT

The first bake will mute the existing transform track and add an additional one, each subsequent bake will add a new track, but will not mute any of the previously added tracks.
