Self-referencing navigation property renames not retained

[DavidBoone]

Love the fact that navigation property renames are now supported! However, ran into an issue where self-referencing relationships' names were not preserved.

I've attached a sample project with an SQLite database. efg generate was run, and then the two properties were renamed to ParentThing and ChildThings. Upon running efg generate those names are lost.
