Review request for ranger, Dhaval Shah, Abhay Kulkarni, Madhan Neethiraj, Mehul Parikh, Ramesh
Mani, Sailaja Polavarapu, Vishal Suvagia, and Velmurugan Periasamy.


Updated testcases.

Bugs: RANGER-3341

Repository: ranger


**Problem Statement:** During policy import on maria DB flavor it was observed that when policy
user is created, return object of XXPortalUser does not have the generated unique id of the
user, hence null value was assigned. null user id can't be used for entries in x_portal_user_role
table for the same user. 

**Proposed Solution:** once a XXPortalUser entry is created, a fresh call need to made to
fetch the same user details and if it has the generated unique id then that id can be used
for creating the roles of the same user.
