Subject: [PATCH 1/2] Check if containment exists before using it.

Without this check Plasmashell crashes in
Plasma::Containment::screen() when called by PanelView::canSetStrut().
This crash happens when the window manager isn't Kwin.

BUG: 511428

Fixes: cbfa8d76d089d7e934d2b4cfe8d917a6df1a37ef (Make all panels reserve space when in edit mode)
