absolute_schema_path is incorrect for if/then constructs #696
Description
I'm using jsonschema 3.2.0 for Python 2.7.14 and am seeing an error in the absolute_schema_path when an if/then construct is involved.
See sample code https://gist.github.com/jason-s/188c226e51f0982ab05538c2d6581c21
which outputs (on my machine) the following, including absolute_schema_path that starts with ['allOf', 0, 'if', 'then' --- the problem is that the if and then keys are at the same level; if we are trying to indicate the then branch, then if should not be in the absolute_schema_path
jsonschema version: 3.2.0
