Remove e2edata dependency from test scripts

[winder]

The scripts in test/ are based on the e2edata block archives and the import subcommand. It would be better to use the private network snapshot and standard fetcher process to initialize Indexer in tests.

If we also want to remove the import subcommand, the create_delete test data will need to be regenerated and rewrite the tests for the new account IDs and app/asset IDs.
