What happened?

If exec_properties for a py_binary or py_test is explicitly set to None, an error of the form

Error: 'NoneType' value has no field or method 'items'

is raised on this line:

In our case, the explicit value of None came from a symbolic macro that used inherit_attrs = "common". This regression was found when trying upgrade from version 1.3.2 to version 1.6.0. Our workaround is to use

if kwargs.get("exec_properties", None) == None:
        kwargs["exec_properties"] = {}

in symbolic macro implementations that create py_* targets.

This regression appears to have been introduced in #529; CC @keith.
