Code review comment for lp:~nicolas-doffay/ubuntu-ui-toolkit/selector-api-break-fix

I propose to keep the "alwaysExpanded" property as it is, and make "expanded" an alias of that one (and mark it as deprecated). That way we introduce the "alwaysExpanded", and we don't break apps that use "expanded".

Also the changes below in the code to change "alwaysExpanded" to "expanded" everywhere can be undone, so this MR will make a lot fewer changes with the same results.
