Remove service date from cache key of SiriTripPatternCache

[leonardehrenfried]

Summary

In today's real time meeting we talked about the indexing of trip patterns in the SiriTripPatternCache and we came to the following conclusion:

• we don't really know why the cache key contains the service date
• even though we are uneasy about it, @vpaturet agreed to just try it out on Entur's staging system to find out if there are negative consequences

Issue

#4002
