Disable export button when no profile is selected

[Jaganathancse]

Export button is enabled only if profiles are selected in Control
Import/Export screen.

@Jaganathancse can you also remove that - observe = {:url => url}.to_json please? Since you've removed the last place that was using that variable..

@himdel I have removed observe = {:url => url}.to_json. please verify.

So.. this works in the UI, switching the choice in the select repaints the whole screen so correctly resets the button.

If this were for keeps, I'd still encourage you to move the JS to a function, and to use .on('change', fn) instead of .change(fn) but the form is on the "being converted to angular" list anyway and it's a minor issue.

Merging 👍 :)
