[x-content-bar] Only place one x-content-bar at a time, make label bold

Original description: cluebars: make the label text bold by default
"Instead of using a custom style class just for that. Also, make the
behavior of NautilusQueryEditor and NautilusSearchBar mimic the trash
and x-content bars (i.e. always set the "question" style class)."

!!NOTE: only doing the x-content bar part!!
