Wizard: Fix 'too short' state in Packages step

Currently, when a search term is entered and then reduced to a single
character in the Wizard's packages step, the previous results are still
shown.
What is expected is that the empty state hinting at the search term
being too short would be shown.

The condition in bodyContent was wrong, because it assumed that the list
of results would be 0 when in fact it wasn't being cleared.

Fixes #3139
