Prepare to enable Hotseat flag in M-81 - Part 3

ShelfWidgetTest::ShelfEdgeOverlappingWindowHitTestMouse is broken when
enabling the hotseat. It is caused by the CL
(https://crrev.com/c/1966428) which fails to set window insets for
hotseat widget. To accelerate the process of enabling the hotseat flag,
only run this test with hotseat disabled.
