Bug: When jobName contains a Chinese character, the floder job creation failed!

The question may be: jobName is encoded two times.
**the first time:**
JenkinsServer.java Line 490
ImmutableMap params = ImmutableMap.of("mode", "com.cloudbees.hudson.plugins.folder.Folder",
"name", EncodingUtils.encodeParam(jobName), "from", "", "Submit", "OK");
**the second time:**
JenkinsHttpClient.java Line 296
queryParams.add("json=" + EncodingUtils.encodeParam(JSONObject.fromObject(data).toString()));

Start in JenkinsServer.java around line 490 and JenkinsHttpClient.java around line 296, then trace how the folder creation parameters and JSON query are encoded. Reproduce folder creation with a jobName containing a Chinese character and confirm that the operation succeeds without unintended double encoding.
