Work around missing search field for MBTA events
MBTA events leave the search
field blank. See, for example, gracedb-playground/G4205.
This caused the following error:
Traceback (most recent call last):
File "/home/emfollow/.local/lib/python3.6/site-packages/celery/app/trace.py", line 382, in trace_task

if event['search'] == 'MDC':
KeyError: 'search'
