Pressed state not cleared if view is disabled in long click handler

bug:2133127

If a View is disabled its onTouchEvent handler uses a shortcut
path for efficient handling which does not clear the pressed
flag. As a result if the view is disabled in a long click
handler the view keeps being in pressed state. The fix is to
clear if needed the pressed flag in the shortcut path
of onTouchEvent.
