Bug:  Misconfigured workspace sites sometimes appear in the Sites section of the back-office admin interface.

The return value of method createSite is not checked for error codes:

Map<String, Object> result = _siteDao.createSite(rootId, initialSiteName, ProjectWorkspaceSiteType.TYPE_ID, true);

If workspace creation fails midway, it would seem the rest of the site creation still goes ahead resulting in a misconfigured site with no workspace attached.

Expected behaviour: Check result for errors before continuing. If creation fails, prevent the workspace and site creation.
