e_client: revert focus instead of setting it to NULL

When closing a client a few different things can happen:
1. Client hides, this will destroy the e_client object, which will
   reverts focus to another client.
2. Client hook del, this will recover focus to the root window if no
   e_client is focused.
3. Client unfocus event, setted the focused to NULL and sets the focus field to 0.

when first 1 happens then 2 or 3 everything is fine. However, it seems
that sometimes first 3 happend, then 2, then 1. Which results in focus
beeing first NULL, then recovered to the root window, resulting in the
wrong things happening.
