resolve replaces path when resolving a fragment

[matt-allan]

\Sabre\Uri\resolve('http://www.mydomain.com/somewhere.json', '#');

Expected output:

http://www.mydomain.com/somewhere.json

(or http://www.mydomain.com/somewhere.json#

Actual Output:

http://www.mydomain.com/#

This seems to be because Sabre\Uri\parse('#') returns "path" => "#".

parse_url('#') returns []. It looks like _parse_fallback is returning the path as #.

Thanks @evert!
