Fix: NewGRF Profile didn't stop if there were no events yet (#10816)

This meant you could have the following situation:
- You start a profile on a GRF with no events, for N days.
- The days pass, the profile should stop. It doesn't.
- The profile will never stop, even if the GRF start generating events.
- There is no real way to discover this, so .. byebye memory? :)
