Copy bags between disks fix (#4776)

* result2pb: fix the wrong number of arguments check-ups (#2945)

Which would cause indexError exception in this case. Also, simply
the file I/O via with statement.

* message: fix msg_received and seq_diff check-ups.

The former should be used if the objects referrred to by the
variables are equal, the laster should be used if two variables
point to the same object.

* message: fix seq_diff according to the intention of comparision

* copy_bags_between_disks.py: code consolidation [#4775]
