Use regexes to test database URIs & DSNs

When there is a username but no password, URI used to leave an orphan
colon in the URI (reported in libwww-perl/URI#13). That bug was fixed in
libwww-perl/URI#31, leading to failures in Sqitch tests expecting the
colon to be present.

libwww-perl/URI-db#23 also changed the DSN of URI::Oracle to specify the
database name with `service_name=`.

So change the tests to use regular expressions to match such URIs and
DSNs, so that the presence of the colon or service name is optional.
Resolves #744.
