Avoid seg fault when no output exists
When no output object such like HDMI, Window Manager crashes on initialize. This patch avoid crashes but no care for hot plug of display. Bug-AGL : SPEC-2136 Change-Id: I30bad0377d0ac646cead0bba1f1ae35952e3fb07 Signed-off-by: Kazumasa Mitsunari <knimitz@witz-inc.co.jp>
