    Recognise lvm command immediately when rescanning for supported actions
    
    Rescanning for supported actions in the File System Support dialog was
    not detecting the removal and restoration of the lvm command.  GParted
    was only updating supported actions after refreshing all devices.
    
    Checking for the lvm command was tied to the refresh of the LVM2_PV_Info
    cache, hence the behaviour.  Fix by always checking for the lvm command
    when requested.
    
    Also remove extra new line from end of an error message in
    load_lvm2_pv_info_cache().
