[autofit] Fix metrics computation.

Problem reported by Markus Trippelsdorf <markus@trippelsdorf.de> and
Nikolaus Waxweiler <madigens@gmail.com>.

* 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.
