Title: Fix from_string when the port is not specified

Before fixing:
```erlang
Eshell V5.10.1 (abort with ^G)
1> uri:from_string("http://test.com").
** exception error: bad argument
in function integer_to_list/1
called as integer_to_list([])
in call from uri:port_to_string/1 (src/uri.erl, line 459)
in call from uri:to_iolist/1 (src/uri.erl, line 562)
in call from uri:update_raw/1 (src/uri.erl, line 558)
