We always leave the workspace switcher zoomed out when we can assume
that the user is actually making use of workspaces. For the default
dynamic workspace behavior, we make this assumption when more than
two workspaces are in use (e.g. at least two workspaces contain windows
plus an empty one at the end). However this test does not make sense
when using static workspaces - in that case, not using workspaces
would be indicated by a workspace number of 1 (in which case the
entire switcher is hidden completely), so add a check for dynamic
workspaces to the condition.
