Subject: [PATCH] Don't call con_fullscreen_permits_focusing with ignore_focus

When we don't modify the focus we aren't risking giving focus to a
container behind the current fullscreen one.

_con_move_to_con can with ignore_focus is called through the swap
command or through con_move_to_workspace for floating containers. This
change shouldn't break the expectations of the callers there.

Fixes issue #3259.
