Wrong runonce arg processing.

Hi! I tried to check my backup plan using:

/opt/znapzend-0.21.0/bin/znapzend --debug --runonce data/nfs --noaction

but I've got a very strange error:

[Sun Mar 13 09:54:16 2022] [info] znapzend (PID=13986) starting up ...
[Sun Mar 13 09:54:16 2022] [info] refreshing backup plans...
cannot open '1': filesystem does not exist
ERROR: no backup set defined or enabled, yet. run 'znapzendzetup' to setup znapzend

the backup plan is:

*** backup plan: data/nfs ***
           dst_0 = backup-main.int.local.net:data/nfs
      dst_0_plan = 1month=>8hours,3months=>1day,6months=>1week,1year=>1month
         enabled = on
         mbuffer = /usr/local/bin/mbuffer:9000
    mbuffer_size = 1G
   post_znap_cmd = off
    pre_znap_cmd = off
       recursive = on
             src = data/nfs
        src_plan = 4weeks=>8hours
        tsformat = %Y-%m-%d-%H%M%S
      zend_delay = 22

I ran znapzend in debug mode, and I've found that it takes runonce value (which equals 1 ) instead of dataset name and passes one to the getBackupSetEnabled function...
