fix(relay): logging.getenv -> crash on import (card loading was broken)

relay_integration.py line 34 called logging.getenv (no such attr), which threw
AttributeError on import -> load_card_from_erpnext() crashed for every caller
(BOC-3 and now UCR filing payment). Drop the bogus line; LOG is set correctly on
the next line. Present since the initial commit.
