Stop executing extension evolutions with hint.
Review Request #3669 — Created Dec. 14, 2012 and submitted
Stop executing extension evolutions with hint. Now when an extension is enabled, only explicit evolutions will be executed. This fixes many problems which can be caused by executing hint generated evolutions. Explicit evolutions can be defined in an extension as they would be in a normal django app.
Created a few simple evolutions on an extension and verified they were applied.
