So currently, if we just do not refresh the db before running this
script what will happen is the relations in the patch groups file will
override the conflicting relations if any.

What I mean is if the Patchwork's database contains the relation: (1, 2,
3) and the incoming relation from the patch groups file is (2, 4, 5).
There is a conflict with patch 2.

The relations in Pathwork after running the script without refreshing
the relations table will be (1, 3) and (2, 4, 5).

If this is acceptable behaviour we can go with this as it is less
destructive in a way.

Thanks,
