c908a6cf - Move complex part of room sorting to a dedicated function

Move complex part of room sorting to a dedicated function Pretty much cut/pasting it in, as there's not really a whole much to help make the code more understandable here. This also includes a comment block longer than the code it describes in hopes it explains away the problem of understanding what it does. Should fix https://github.com/vector-im/riot-web/issues/8861
