   Looking at the history of this I found the following. 
   
    * This issue was opened about a test the verifies the UserFateStore will 
retry when the random id it picked for a new fate id exists.  It retries up to 
5 times and then fails, the test that only exists for UserFateStore checks 
this. 
    * The MetaFateStore does not retry and does not have a test for the case of 
a collision.
    * These changes referenced in this issue were made before #4388 which 
changed the fate id type from 64bit to 128bit.  This change dramatically 
decreases the chance of collision to the point where maybe it should not be 
expected.
   
   With the change from 64bit to 128bit wondering if instead of implementing 
and testing the behavior in both stores if we should simplify the expectation 
to fail on any collision (instead of allowing 5) and test that in both stores.
