Fix the issue swiping gesture is wrongly enabled during recording

[Reproduction Step]
1.  enter camcorder mode
2.  open the pie
3.  start recording
4.  do a swiping gesture from right to left, then the camcorder will be
    slided to the photo view, and the icon error
    About the step 4 the standard behaver should be: when recording, the
    screen will ignore swiping gesture, so can not slide to the photo view
[Root Cause]
1.  startVideoRecording() -> setSwipingEnabled(false) -> disable swiping
    gesture, ignore swiping gesture
2.  startVideoRecording() -> enableCameraControls(false) -> onPieClosed()
    -> setSwipingEnabled(true) -> enable swiping gesture
[Resolution]
    when close the pie, check whether recording firstly, if recording,
    setSwipingEnabled(false), else setSwipingEnabled(true)
