commit a54f420b21c124143c377148bcee2ecaeaa355e7

    Send correct 400 for missing partition with _find (#1936)
    
    When sending an incorrect partition query e.g:
    /parition/_find, send a 400 with the message:
    
    Partition must not start with an underscore
    
    This makes it consistent with all the other partition requests
