Don't create empty workspaces on restart

Browse Source 
This fixes a bug I introduced in #1921. When restarting i3 in place a
stray workspace was created on the root_output during restart. On first
start, this workspace would have been moved to the first real and empty
output.

However, this does not produce the desired result during restarts when
workspaces are alread present on all real outputs. The stray workspace would
still be added to the first real output which already contains some
workspaces. Thus, adding a new empty workspace to it.

Fix this by delaying creation of the root output's workspace until it is
known whether the output is active or not.

Fixes #1940
