- The context should be properly expanded also when calling a Python procedure

- Refactored the logic for executing a request and wrapping the response common to procedures, crons and event hook decorators into platypush.common.exec_wrapper

- Added mock getvalue() method to Logger to prevent PyCharm failures in the tests when sys.stdout is redirected to the Logger object
