Fix url_fixer_upper_unittest two-phase lookup problems.
Fix url_fixer_upper_unittest two-phase lookup problems.

The operator<< for url_parse::Component needs to be declared
in the same namespace as its parameter type, in this case url_parse.

Otherwise Clang fails to compile this because it is more strict on the Standard.

See http://clang.llvm.org/compatibility.html#dep_lookup for more info.
