Add "setFullScreenMode" to OCA.Files.Sidebar object
Add "setFullScreenMode" to OCA.Files.Sidebar object

In Nextcloud 22 "setFullScreenMode" was added to OCA.Files.Sidebar. This
method is expected and used by the viewer, so even if the sidebar style
is not changed to set it in full screen mode the method needs to be
there.
