Incorrectly stripping python path names

[Will-20]

There is a bug on line 61 here, if a path ends in y, for example proxy.py, then this gets incorrectly stripped to prox instead of proxy.

Lines 56 to 63 in ce4764f

	def path_to_import(path):
	"""Convert a path to import."""
	if path.name == '__init__.py':
	import_path = str(path.parent)
	else:
	import_path = str(path).rstrip(PY_EXTENSION)
	return import_path.replace('/', '.')
