Improve assertion in FindReplTupleInLocalRel(). 

The first part of the assertion verifying that the passed index must be PK
or RI was incorrectly passing index relation instead of heap relation in
GetRelationIdentityOrPK(). The assertion was not failing because the
second part of the assertion which needs to be performed only when remote
relation has REPLICA_IDENTITY_FULL set was also incorrect.

The change is not backpatched because the current coding doesn't lead to
any failure.
