Remove Test Banner and Icons in the background on the landing page

• Remove the red banner and the little symbols on the home page. (Do not remove the red banner for drafts).

• Replace the "no data" message when the filter combination does not give any results with a message making clear that the user has to select another Filter Combination. But I think this will be solved anyway (or in most of cases?) with the new functionality on filter selection; the message should not be "no data", but rather "for this filter no data available" or similar:

@sosiology I am not really sure how we should change the "No data" message, as the information on selecting other filters is already there just below a title?

Should it be:
title: "No data available for current filters"
description: "Select another combination of filters"?

I think that in general it should be solved in most cases by cascading filters (@ptbrowne correct me if I'm wrong :)).

I think your proposition is good @bprusinowski , "Please try with another combination of filters".

I think in most cases it would be solved yes, but still I think improving the title/description just a bit like you did is a good step forward.
