Don't put timers with ID == 0 into the global timer map.

A return of ID == 0 from the embedder means the timer was not
created (see public/fpdf_formfill.h), although few embedders
actually conform to this convention.

Firing a timer with ID == 0 will thus do nothing since there can't
be such a timer in the map.
