Do not assert that new URI port is same as old port
When handling 301 redirects from http -> https on Erlang 21.0.1, the
following error is encountered:
```
8> Options = [].
9> httpc:request(head, {"http://rhye.org", []}, Options, []).
{error,{shutdown,{{error,{badmatch,443}},
[{httpc_response,resolve_uri,7,
[{file,"/usr/local/lib/erlang/lib/inets-7.0/src/http_client/httpc_response.erl"},
{line,431}]},
{httpc_response,redirect,2,
[{file,"/usr/local/lib/erlang/lib/inets-7.0/src/http_client/httpc_response.erl"},
{line,396}]},
{httpc_handler,handle_response,1,
[{file,"httpc_handler.erl"},{line,1052}]},
{httpc_handler,handle_info,2,
[{file,"httpc_handler.erl"},{line,283}]},
{gen_server,try_dispatch,4,
[{file,"gen_server.erl"},{line,637}]},
{gen_server,handle_msg,6,
[{file,"gen_server.erl"},{line,711}]},
{proc_lib,init_p_do_apply,3,
[{file,"proc_lib.erl"},{line,249}]}]}}}
```
This seems to be caused by the following code in `resolve_uri`:
```
resolve_uri(Scheme, Host, Port, Path, Query, URI, Map0) ->
case maps:is_key(scheme, URI) of
true ->
Port = get_port(URI)
```
The value of `Port` passed in to `resolve_uri` here is 80, since the
original URL is http. However, since the redirected URL is https, the
`get_port` call returns 443, which is not equal to 80, and crashes.
Assigning to a new variable seems to fix redirects.
