test_property_decorator_doc_writable no longer modifies
the class in module level.

Also align the parameter naming in binascii to be consistent with zlib.

The previous fix only handled the case of the parent package of __main__
failing to initialize.

Also make the "Error while finding spec" formatting slightly more appealing,
and document and test that the module name must be absolute.

These were added in revision b71cda2f48c6.
