[autofit] Fix metrics computation.

Problem reported by Markus Trippelsdorf <[email protected]> and
Nikolaus Waxweiler <[email protected]>.

* src/base/ftobjs.c (FT_Request_Size): Trigger recomputation of
auto-hinter metrics.  Without this change, multiple size changing
calls for a single face fail.
