Okta SCIM test username update request

Similar to this thread I was testing my SCIM API using the Runscope testing instructions and failing since our db stores the username in lowercase. According to the SCIM spec this is valid since the username is case insensitive.

Could the test script to be updated with case insensitivity in mind? This would better match the expected behavior, and reduce false alarms for other devs using these testing tools in the future.
