test: e2e test reliability improvements (docker#10950)

* Use unique project name prefixes (some of these tests assert
  on output using the project name as a magic string, so could
  be impacted by other tests with the same project name prefix)
* Tear down port range project before starting to try and avoid
  race conditions with the engine and port assignment
