Subject: [PATCH] Fabric: Use `ShadowNode::sameFamily` instead of `getTag()` to
 check for same family

Summary:
We used to use `getTag` to check that some two nodes are clones of each other, not we have a dedicated method for that that exactly ensures that without reling  on a sideeffect (wich tag equality is).
That is just much less error-prone.

Changelog: [Internal] Fabric-specific internal change.
