popovers: Hide message action popover on revealing muted user messsage.

When muted user's message is revealed, popover should have
an option for hiding the message again. But in case if the
popover is already open while message is being revealed then
option for undo reveal in the popover could be out of sync.

To avoid this, we hide the message actions popover before
revealing muted user's message.
