[Dropdown] Fix #5231 Clicking on the dropdown icon will generate multiple hits to the server (when no results are returned)

I resolved the loop by adding the noResults message in queryRemote (which is specific to this scenario, so it seemed appropriate) if the length of results is zero

This is a bugfix, we are also affected. Could someone please look into it?

I've added a solve in next patch, that is similar in style to this PR. Credit in release notes.

I am not sure if I should post this as a new bug.
I receive the array as an object.

So, from @jlukic fix,
hasRemoteValues = ($.isArray(values) && values.length > 0)
is set to false because of isArray.

Do you think it could be replaced by
hasRemoteValues = !$.isEmptyObject(values) ?
Or do you really have to check if it is an array?

My object would look like
{ 0 : {name: "test", text: "test", value: "101"} }
