Use .equals() to compare schemas

[cchandurkar]

If SMT clones the schema of the object for any reason, it does not have the same "hash" as original schema but structurally it's the same. Using !.equals() instead of != will allow SMTs to properly clone the schemas.

lgtm!

Thanks for signing the CLA. This is good to merge. @sfc-gh-japatel @sfc-gh-rcheng

@sfc-gh-japatel any thoughts on this? I've seen this issue popping up a multiple times where a schema closed in SMT doesn't have the same hash as original schema and this equality check fails even when the schema is structurally identical. Using .equals() fixes it.

@sfc-gh-mbobowski and team to also help review any implications.
