form: Fix bug in populate()

There was a problem with processing enum type fields.  The way all other
field types are asserted to be 'defined' is via:

        isset($field) && $field != ""

Which works perfectly fine, and is exactly what we want.  However, with
enums the second part of that && can bite us if "" is in the list of
acceptable values.

This commit removed that half of the check (only for enum values) so
that the empty string may be an acceptable enum value.  If "" is not in
the values array, then the check is implicitly reinstated.
