[IMP] base: do not fill description_html with description for applications

For applications we don't want to have an html description based on the
text field description. This description is just a small summary and does
not add much value to the Apps view. If no description_html is given let
us just use the newly-introduced discover feature instead of filling
ugly content in html description.

This commit is related to task 47179 and PR #22689.
