fix($http): do not encode special characters @$:, in params

encodeURIComponent is too aggressive and doesn't follow http://www.ietf.org/rfc/rfc3986.txt
with regards to the character set (pchar) allowed in path segments so we need
this test to make sure that we don't over-encode the params and break stuff
like buzz api which uses @self.

This is has already been fixed in `$resource`. This commit fixes it in a same way
for `$http` as well.

BREAKING CHANGE: $http does follow RFC3986 and does not encode special characters
like `$@,:` in params. If your application needs to encode these characters, encode
them manually, before sending the request.
