For a status type attribute, if a status type is being removed from the type values, it fails to validate if there's an existing object with the same status type

Steps to reproduce:

• Have a schema with an object type with status type attribute
• Create a few status types and add it in the type values to the attribute
• Create a few objects with one status type - A
• Remove A from the type values in the attribute

Expected behaviour:

An error should be thrown when an existing object has that status type value

Actual behaviour:

No error is thrown, that status type is removed from OTA and the object with that removed status type still exists with that status
