Fixed escaping server relative URLs

[jerry-sky]

Given value that is a path, like /sites/Site/O'Reilly, needs to be enclosed within quotes:

GET https://{site_url}/_api/web/GetFolderByServerRelativeUrl('/sites/Site/O'Reilly')/Files

because the quote within the name of the folder O'Reilly is messing up where the argument ends,
it needs to be escaped, like so:

GET https://{site_url}/_api/web/GetFolderByServerRelativeUrl('/sites/Site/O''Reilly')/Files

before sending it to the API.

rawurlencodeing it doesn't solve the issue, the URL is decoded before it is evaluated by the API it seems.

Example error when you don't escape the quote characters:

{
  "error": {
    "code": "-1, Microsoft.SharePoint.Client.InvalidClientQueryException",
    "message": {
      "lang": "en-US",
      "value": "The expression \"Web/getFolderByServerRelativeUrl('/sites/Site/O'Reilly')\" is not valid."
    }
  }
}
