Change message in arrivals when the stop name is found
Summary: Fix T1368
Test Plan:
Check stop 17369, or a stop that is not serviced at the moment (like late at night). It suffices to have a name in the DB (therefore, present of the map)
If the message says "no arrivals found" instead of "no stop with this name", it works.
