Updated non-SDK restrictions

The goal of this issue is to test for non-SDK interfaces in the app using the instructions provided here. If the app relies on non-SDK interfaces, we should begin planning a migration to SDK interfaces or other alternatives.

Found at least two uses of non-SDK APIs:

Reflection unsupported Landroid/text/TextPaint;->setUnderlineText use(s):
       Lorg/wordpress/android/widgets/ColorUnderlineSpan;->updateDrawState(Landroid/text/TextPaint;)V

Reflection unsupported Landroid/widget/TextView;->mEditor use(s):
       Lorg/wordpress/mobile/ReactNativeAztec/ReactAztecText;->setCursorColor(Ljava/lang/Integer;)V
