In a search view, write text in the input, then hit enter to select
the facet.
Before this commit, the search view was detached and then reattached
when the control panel was refreshed. This led to loosing the focus
momentarily and erasing any supplementary input one might have typed
*during* the rpc call.
After this commit, if the search view is the same as before, we don't
detach it in the first place. Thus, the input is conserved in this
situation.
