Always submit after texture uploads
Ensure GrContext::submit() is always called after either
Bitmap#prepareToDraw() or if DrawFrameTask skipped drawing.
In either case texture uploads & deletions will be scheduled,
but without the submit they won't actually be performed. This
can end up running out of RAM.

Test: manual test app
