Add unit test for adding a missing package

This fails because the add operation is not aware of package settings,
and therefore adds a package dotfiles as it normally would - as
a toplevel symlink.  The problem arises when a user attempts to sync and
the expected symlink layout is not as it should be.  With the force
option, this can lead to deleted files with no way to recover.
