Fix file! not returning filename in some cases

Browse Source 
There are scenarios where load-file-name is set, but load-in-progress is
not. It is safe to assume the value of load-file-name is always what we
want.

Also: file! now throws an error if it can't find the directory.
Otherwise we have to deal with roundabout errors from other places that
expect file! to never fail.
