Password update times out due to user id search among all the userstores

[rksk]

Describe the issue: It was observed that when there are multiple userstores in the system, user id is searched on all the user stores during the doPostUpdateCredentialByAdminWithID event for non-uniqueID userstores.

At [1], the userstore object contains an instance from the correct userstore in which user resides. But the flow goes on and extractedDomain is null at [2], then it again searches for this user id on all the userstores.

How to reproduce: Create multiple userstores with non-uniqueID classes and try to update password in one user from any userstore.

Expected behavior: It should not search on all the user stores during the post events since we already know that where the user resides.
