Plasmashell already handles closing the expanded representation
when the config dialog is openend (or keeping it open if it's
pinned).
Tested with opening system tray and applet configs both when pinned
and when unpinned.
BUG:440263
Before this patch, the system tray always animated sliding to the left when switching between items. Now system tray items will slide according to their order on the panel. Clicking an item to the left of the active icon will cause the sliding animation to slide that direction as well, and same for the an item to the right of the active item.
Refactor and simply logic of "expanded" state when dialog with active applet or list of hidden applets is shown.
Fixes a problem with keyboard shortcut activation.
It also fixes a bug when dialog closes on "go-back" button click.
