Parse URLs without a forward slash before query

[jonathonmcmurray]

Currently, URL parsing splits hostname from path by searching for /

e.g. foo://example.com:8042/over/there?name=ferret

• here, the path (including query) is /over/there?name=ferret

In rare circumstances, it could be possible that a URL has no "path" but does have a query e.g.

foo://example.com:8042?name=ferret

In current implementation, a / is required before the ? to properly parse the path as /?name=ferret.

Should handle this automatically & insert leading / to path if necessary
