By setting the deprecation version for KRunner to 5.91,
the negated deprecation wrapper will evaulate to true and
we get compatibility typedefs.
This way we do not need to add the typedefs manually or
add `using namespace Plasma` to the plugins.
Task: https://phabricator.kde.org/T15140
The test should make sure the chrome bookmarks and profile reading
works properly and not test the conversion logic.
In the previous commit a dedicated test has been added
for the conversion and relevance logic.
