Fix the null pointer in operations json list.

[Malith-19]

Purpose

Fix wso2/product-is#19409

This issue occures, when a invalid operation schema field given since it only accepts Operations` field. Once json schema not contains this filed correctly it will create a null pointer and raise an error in a for loop used to iterate that operation list.

Goals

Handle the internal error in PATCH scim2/v2/roles/{id} API.

Approach

• Check weather operation list is null first.
• If yes, then it checks json schema contains operations field and throws an bad request error error with invalid json schema.
• If operation list is null and still not has operations throws an bad request error with default error description.
