Tabs still displayed even when empty

Added patch only hide content if Views are empty

Added arguments to the view in the patch.

hii , #6 is working for me .

Lets ad some test coverage for this please.

This wasn't working for me, empty views loaded with ajax were still showing, so I made some adjustments and rebased for 4.0.x

MR 24 is for 4.0.x

Here is a patch for composer

Still no test coverage.

While digging into this I had a thought.

There is a difference with an empty view because views permission/argument validation fails vs. a view with no results.
And do we want to hide the tab in both cases? There are times when you would want the content of the no results handler to display on certain views.

Perhaps there could be a setting per views tab allowing them to specify no results vs no access?
