Summary:
Commit 174aa217 created a new
issue where the activity switcher would not hide anymore when
switching activities with the Meta-Tab global shortcut and
releasing the keys under one second.

This patch fixes this by unconditionnal toggling the activity
switcher visibility if it should be hidden, but keeping the
timestamp condition before showing it, so that both Meta-q and
Meta-Tab behaves correctly.
