Subject: [PATCH] networkaddress: fix parsing of uri with @ after authority

Make sure that the @ sign is inside the authority part before attempting
to parse the userinfo. We do this by checking if the @ sign comes before
any of the possible authority delimiters.
Add unit test to verify parsing of ftp://ftp.gnome.org/start?foo=bar@baz
