Fix code renaming in windows

[jneira]

• Taking in account terms between backquote and single quote
• In my hie.log i'be observed that the quickfix request is

    "textDocument": {

    },
    "range": {
      "start": {
        "line": 0,
        "character": 11
      },
      "end": {
        "line": 0,
        "character": 11
      }
    },
    "context": {
      "diagnostics": [
        {
          "range": {
            "start": {
              "line": 0,
              "character": 7
            },
            "end": {
              "line": 0,
              "character": 15
            }
          },
          "message": "* Variable not in scope: butStrLn :: [Char] -> t\n* Perhaps you meant `putStrLn' (imported from Prelude)",
          "severity": 1,
          "source": "ghcmod"
        }
      ]
    }
  }
}

• So the suggestion putStrLn is between ` and ' instead ‘ and ’ (the delimiters expected by code)
• Not sure why it is different in windows but the code now pass the tests 1 and 2 of Error in windows detected by the functional test suite #1391 .
