'main': Work around type -w bug in zsh

Browse Source 
Even if 'type -w' returns 'none', it still hashes it in $commands:
http://www.zsh.org/mla/workers/2016/msg01583.html

Before 12b879caf7, we ran 'type -w'
in a subshell, so this bug did not manifest. Now that we don't,
the $commands array is poisoned with invalid entries.

To prevent this, while still keeping the perfomance benefit of
avoiding the subshell, we make sure we remove invalid entries
from $commands again.
