fix: mark run as done when skipif is true

[saranyailla]

Issue #, if available:

Description of changes:
Currently, when skipif evaluates to true, RunStatus is set to OK in the result. But, RunStatus.OK is currently not handled in by the Run handler. We could either add a case to handle OK or mark the skipif RunStatus to NothingDone.

This doesn't impact INSTALL lifecycle as it only cares when RunStatus is Errored.

	if (runResult.getStatusCode() == null) {
	serviceErrored("Script errored in run");
