Garbage collector doesn't work with varbinary primary index

Environment

Tarantool: 2.11.2
Vshard: 0.1.28

Space:

---yaml

Description

If I trigger a rebalance on the space with a primary key with varbinary fields, the buckets will be moved to new replicasets. However, they will not be deleted from the old ones.
