    base-manager: Only use search criteria Filterables in the "all" filter
    
    A subsequent commit will track GMounts representing USB storage and
    PTP devices and represent them as GMount-backed sources. These sources
    shouldn't contribute to the SourceManager's "all" filter. This demands
    finer control over the filter generation process.
