Fixed following issues after React Porting:

1. Unique constraint should not allow changing values for deferrable, deferred, included columns.
2. Primary keys should not allow changing values for deferrable, deferred, included columns.
3. Foreign keys should not allow changing match type. The referenced table name is empty.
4. Exclude - Column/Expression has incorrect values.
5. Save should not be enabled when Custom auto-vacuum is enabled but none of the parameters are edited.

Fixes #6777
