Revert "Fix invalid URL escape"

This reverts commit 60d9f56718b789889a569589c34145df01a507d7.

The workaround in this commit breaks a uri
because what QueryEscape does is to percent-encode the given string.

e.g.
  fmt.Println(url.QueryEscape("/foo/bar?token=xxx&uuid=1234"))
  // => %2Ffoo%2Fbar%3Ftoken%3Dxxx%26uuid%3D1234
