There seems to be a "general" settings field issue with Zanata where if a user changes a field - e.g. email, project id etc - and then undoes that text without submitting the change, the field will complain that the "ID is not available"
1. Go to a project, select Settings
2. Add _thing to the project ID, but don't submit
3. Remove the _thing
Error: "This Project ID is not available"
It should not show this, as it suggests to the user something is wrong (when it is not)
