SAFEGUARD: Check upstream definition string



Obviously John S. Stefano ran into a cryptic problem because of a given malformed spooler/upstream definition string. This introduces a runtime check in cvmfs_server catching such mistakes with a descriptive error message instead of an assert-crash in the spooler.

Note: this also contains a fine-tuning in testcase 023 which I apparently checked into my local master by accident.
