NO TICKET: only write to transfer logs for transfer scripts

[jacob-a-brown]

Why

This PR addresses the following problem / context:

• the transfer logs should only be written to during transfer scripts, not during tests

How

Implementation summary - the following was changed / added / removed:

• remove from transfers.transfers import erase_and_initalize from tests/__init__.py and use erase_and_rebuild_db from core/initializers.py instead. Otherwise the transfer logger will be instantiated and used for tests

Notes

Any special considerations, workarounds, or follow-up work to note?

• Use bullet points here
