Drop postToURL for ordering case runs

[tkdchen]

This is related to taggleSortCaseRun. A major thinking is how to remove unnecessary form data from the POST request sent to the ordercaserun/ endpoint, since the endpoint only requires test case runs ids. The unnecessary form data includes the search criteria.

Or, on the other hand, maybe it is also worth to consider if it is necessary to remove those search criteria from form data.

AC:

• Do not rely on postToURL.
• No regression.
