Listing of files and folders on dataset page calls server side twice

[lmarini]

Describe the bug
When the dataset page loads, the listing of files and folder calls the server twice.

There is two calls in the javascript console. Need to figure out which one is the second call and remove it. Example call:

POST https://clowder/datasets/59f36b364f0c8f24de9dc222/updatedFilesAndFolders?limit=20&pageIndex=0&space=59f37bfb4f0c8f24de9dde9b

To Reproduce

1. Load any dataset page
2. Look at javascript console

Expected behavior
One call to sever should suffice.

Correction: Re-loading the page only calls the server side once. It is when the sorting of files in the dataset changes (this has to be enabled in the instance) that the call is triggered twice. So it is something to do with the select2 eventing.
