[dbapi] Fix broken inmemory:// URLs parsing (closes #3225832) ParseResult.path is what comes after the "domain name" in standard URLs. So in the case of 'inmemory://<instance' URLs, it is always empty. ParseResult.netloc contains the "domain name" part that we really want.

from os.path import join
assert __file__.endswith(join('scripts', 'script1.py')), __file__
assert '__main__' == __name__, __name__
assert [] == __args__, __args__
