Escape the database path in the SQLite connection string (closes #518)

SQLite reads a file: URI's path only up to the first ? or #, and
decodes %XX escapes in it. With a data directory such as
/srv/hooks#1, every database opened the one file /srv/hooks. The
connection string is now built with url.URL, which escapes the path,
and OmitHost keeps a relative path relative.

Tests open databases in a directory whose name holds #, ? and %, and
at a relative path, and check through PRAGMA database_list that each
opened the file asked for. A handlers test comment that blamed # in
the temporary directory's path is dropped, as that is no longer true.
