Commit a757dda replaced the awful.client.movetotag call with c:tags()
in the tag property handler. Which introduced a regression when more
than one screen is used. The awful.tag.withcurrent function was being
called even when there was a valid tag property. Now the clients
screen is set to the tag screen to ensure the client is moved to the
correct tag and screen.
