[keycloak-user] Custom UserStorage module issue

[Bill Burke]

I think I may know what the problem is.  The registration page is split 
into multiple different processors.  The user is created in one 
processor and the flow context is set to the user.  The problem is, then 
context stores the user as an id and every time a processor needs the 
user it does a lookup by id.  So, what I think is happening in your 
situation is that you are creating multiple different proxy objects in 
the same transaction and your transaction commit logic is confused by this.

I  don't think the Keycloak runtime can keep track of UserModels loaded 
in the transaction and bypass invoking the UserStorageProvider methods.  
Why?  Mainly because of bulk query methods....  So, you'll have to keep 
track of the proxies you create in your provider.  Hopefully that makes 
sense.
