       post-receive: fix warning in script for example when pushing deleted tags
       
       the "new" variable would be zero:
               remote: fatal: bad object 0000000000000000000000000000000000000000
       
       NOTE: when pushing new tags the "old" variable would be zero, this was
             already fixed.
