fix bug introduced with SK_IGNORE_CUBIC_STROKE_FIX where we no longer respected
subDivide limit. This caused problems with degenate paths (too much recursion).

The fix was two parts:
1. decrement the subDivide limit as we recurse
2. up the limit for cubics to 7, to match our current quality

added unittest that replicated the too-much-recursion bug.
