    search-engine-recent: Give back a ref to idle
    
    Since commit 4c6d4eea995a66e80fb21ee83b66954d1ce71c08, we don't haven't
    been increaseing the reference count of the recent search engine when
    not running in a thread.
    
    But the idle callback unref's it anyway, which causes the recent engine
    to be destroyed, while NautilusSearchEngine still holds a referenc to
    it. This causes a crash when trying to cancel the recent engine.
    
    Restore reference count increase to fix this.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/692
