workspace_get_initial_output: handle focused layer1.0-rc2

When a layer surface is focused, `seat_get_focused_workspace` will be
NULL. This changes `workspace_get_initial_output` to use output of the
focus inactive. If the focus inactive is also NULL, then either the
first output or the noop output will be used as fallbacks.
