This fixes user environment setup for sessions which doesn't successfully go through a shell init. Note we don't go through `sessionVariables` as we want the wrappers to have highest priority. It would also cause wrapperDir to occur twice when in shell sessions, as shells use `sessionVariables` too while prepending wrapperDir in a custom snippet. In particular logging in and out of gnome-shell could result in a broken path without this fix.
