Added some more tests.

Removed the validation in the schema - it was adding complexity, let the unique constraint on the db throw the exception. This should only ever happen on a race condition which seems unlikely (two people changing a service to the same name at the same time)
Do no set debug=true to the test config. If debug=true it changes the behaviour of the error handlers, throwing the exception rather than returning a 500.
