fix(desktop-picker): Populate list of desktop app windows to share

Fix bug introduced via #12994 where id was changed and "-tab" was appended. Due to this the selected tab was not anymore working and empty object was returned here: 05da37b56d/react/features/desktop-picker/components/DesktopPicker.tsx (L270)

Originally part of #13096 by @dudumanbogdan, but pulled ahead to fix application
window sharing via Electron desktop app.

Fixes: jitsi/jitsi-meet-electron#857
