fix(wm): avoid dupes when following links

Browse Source 
When adding selective handling of Uncloak events, a regression was
introduced where, for example, when clicking a link from Discord on
Workspace 2, a Firefox instance on Workspace 1 would be moved to
Workspace 2 to open the link, but when moving back to Workspace 1, a
ghost tile would be left, and the Firefox instance would be duplicated
across two workspaces.

This commit fixes this regression and makes the handler a bit easier to
reason about while also removing unnecessary early return statements
which prevent notifcations from getting sent to subscribers.
