Setting the Take Recorder Panel's mode several times through scripting can cause the panel to become invalid

The bug can be worked around by checking the Panel's mode before setting it.

1. Create an editor utility widget
2. Add a button to the widget
3. In the widget's event graph add an event for the button's on clicked
4. Call "Open Take Recorder Panel" and "Set Mode (Recording into Level Sequence)" from the event
5. Compile and save
6. Run the widget
7. Click the button three times in a row

RESULT:

The first click will set up the take for recording, the second click will invalidate the panel, and the third click will fail as a result (see log for warnings).
