Glyph cache optimization

Browse Source 
Precaching at startup was not working. One-liner fix to init the caches
so that precaching would kick in earlier, saving time at startup by avoiding
the multiple-upload issue of caching at render time.

Issue #6893691 long app launch time on manta for some apps comparing to nakasi/stingray
