Windows: Force rebuilding Freelance directory in AddMount and AddSymlink

cm_FreelanceAddMount and cm_FreelanceAddSymlink is supposed to
return the allocated FID of the entry that was added.  However,
cm_NameI is called to perform the lookup without forcing an update
of the Freelance fake directory.  As a result the entry may not be
found.

Force an update prior to calling cm_NameI() by using
cm_clearLocalMountPointChange() and cm_reInitLocalMountPoints()
if required.
