test: hostname format check fails on empty string

Assert that hostname format validation fails gracefully on empty strings. This is especially for Python `jsonschema` library that raises an unexpected ValueError exception on `hostname` check (python-jsonschema/jsonschema#1121). Adds similar test for: * draft3: host-name * draft4: hostname * draft6: hosntame * draft7: hostname, idn-hostname * draft2019-09: hostname, idn-hostname * draft2020-12: hostname, idn-hostname * draft-next: hostname, idn-hostname
