local: fix -L/--copy-links with filters missing directories

In this commit

8d1fff9a82 local: obey file filters in listing to fix errors on excluded files

We introduced the concept of local backend filters.

Unfortunately the filters were being applied before we had resolved
the symlink to point to a directory. This meant that symlinks pointing
to directories were filtered out when they shouldn't have been.

This was fixed by moving the filter check until after the symlink had
been resolved.
