    gdbusobjectmanagerclient: Don’t warn if removing an interface fails
    
    If an `InterfacesRemoved` signal is received for an object which doesn’t
    exist in the local map of interfaces, don’t emit a warning.
    
    This seems to happen in the real world (see #2401). Without a trace of
    the D-Bus traffic it’s not possible to know exactly what situation is
    causing this, but it seems possible that the peer could disappear and
    its `notify::name-owner` signal could be processed before its
    `InterfacesRemoved` signal, or something similar.
