function p.parseComponentIfApplicable(frame)

Parse component for given page. Parse the component template specified by the class definition data, or fall back to default if class definition does not have "Class" in the ws-base-props slot.

Frame arguments used:
- component : (sidebar / subheader / footer)
- page : (pagename) page for which the component should be parsed, defaults to current page

debug console test:
=p.parseComponentIfApplicable(mw.getCurrentFrame():newChild{title="whatever",args={[1]="sidebar",["page"]="Template:Sidebar item"}})
