Fix mising ANTI_ALIAS_FLAG when resetting Text Paint

Summary:
D63303172 introduced a bug showing truncation on versions of Android <= 28. I tracked this down to `ANTI_ALIAS_FLAG` getting cleared when we reset the paint. This applies it again after resetting, for consistency with previous behavior, and TextView.

Changelog:
[Android][Fixed] - Fix mising `ANTI_ALIAS_FLAG` when resetting Text Paint
