Subject: [PATCH] Fix AttributeError thrown when no extensions were detected
 (Fixes #91).

The bug was introduced with the commit ecc67a3 and was caused by the
initialization of an empty Changes object.

This fix makes sure that the __iadd__() method properly handles empty
change sets and returns a satisfactory object back when completing
execution.
