common: fix subgraph pagination chattyness, fix subgraph pagination

[dwerner]

Bump subgraph query page size to 1000 as per #1058

Also fixes subgraph pagination that sometimes results in duplicates in this test:

https://github.com/graphprotocol/indexer/blob/main/packages/indexer-common/src/indexer-management/__tests__/helpers.test.ts#L355

Which is leading to this failure in tests sometimes:
