Ticket #47493 - Configuration Tab does not work with FIPS mode enabled
    
    Description: To invoke Manage Certificate window, NSS slot needs to be
    found by looking up the token name.  When the token name is "internal
    (software)", the slot is supposed to be found by PK11_GetInternalKeySlot
    that provides the support for FIPS instead of PK11_FindSlotByName.  This
    patch calls the right api based upon the token type.
