Fix several issues in the test
Fix several issues in the test

- string was not imported
- __exit__ takes exception info, not no arguments
- signal.alarm(0) silences the current alarm, if there is one. The default
  handler for Python kills the process, so the alarm has to be canceled
  before it does that.
- Fix syntax in the config file
- CommandPie is not a class
