Since this branch was brewing for a while, changes happened in the meantime.
Current window management approach results in secondary windows being
destroyed once they are hidden. Since those windows are managed by
`std::unique_ptr<>`, we can't just [temporarily] increase their refcount
to avoid use-after-free situation, so retrieve updated top-level windows
list every time we hide one instead.
* fix(gtk): prevent duplicate shortcut folders
This prevents duplicates if the recent destination is also a system
shortcut folder.
