Export/Import : When relationship is updated to block tag , the imported lineage doesn't have the updated relationship

PROBLEM STATEMENT:

Export/Import : When relationship is updated to block tag , the imported lineage doesn't have the updated relationship

 
STEPS TO REPRODUCE:

1. In cluster1 create lineage as the following:
2. table1 {}(edge1){}>  process1   (edge2){}> table2
3. Update edge1 relationship - set propagation from table to process as None
4. Add tag to table1 , the tag is not propagated to process1 and table2
5. Now export the table2 entity to cluster2
6. In cluster2, process2 and table2 have the tag propagated from table1

CURRENT BEHAVIOUR:

edge1 relationship in cluster2 doesn't have the propagation blocked.

EXPECTED BEHAVIOUR:

edge1 relationship in cluster2 should have the propagation blocked.

OCCURRENCE:

Consistently reproducible.

HISTORY OF FAILURE:

Test case added newly
