set correct path on redirect to filename

[ontarionick]

I apologize if this is heinous - I'm completely new to how HTTP works, and this is a guess at how to fix a problem I've had a couple times.

When I make a GET request to a certain website, I get a 302 response with the location header set to the same filename (but without the full path) with a different query string. When attempting to follow that redirect, httparty makes a GET request to a broken url and I get an getaddrinfo: nodename nor servname provided, or not known (SocketError) exception.

For example:

• GET http://example.com/foo/bar
• Server responds 302 with location header set to bar?token=123
• On https:/jnunemaker/httparty/blob/master/lib/httparty/request.rb#L59, #uri sets new_uri to http://example.combar?token=123
• Sadness :(
