* Merge Identity Entities if two claim the same alias
Past bugs/race conditions meant two entities could be created each
claiming the same alias. There are planned longer term fixes for this
(outside of the race condition being fixed in 0.10.4) that involve
changing the data model, but this is an immediate workaround that has
the same net effect: if two entities claim the same alias, assume they
were created due to this race condition and merge them.
In this situation, also automatically merge policies so we don't lose
e.g. RGPs.
