Set refresh_search async searchresults load to use bootstrap

If you search a person by it's full qualifier and async results are used (person not known on the local pod) there is a delay of 10s until the results are asynchroniously loaded. The results ajax-code returns the blueprint-version of `_aspect_membership_dropdown`, but the calling page is rendered with bootstrap.

I added the refresh_search to the list of methods which will use bootstrap for rendering.

This solves #5240 .
