FloatingToolbar: Hide panels when they're invisible.
This patch sets the visibility of a panel to INVISIBLE when it's
alpha is 0. This will ensure that a user cannot interact with a
view that cannot be seen. Not doing this resulted in a bug where
the user will tap on an area of the toolbar and activate an
unintended action.
It also removes the redundant mResetOverflowButtonDrawable. It's
actions are already performed in setPanelsStatesAtRestingPosition.
