Improve performance of triggered chat commands

When the trigger endpoint is called, it has to find the right service for the given project. However, the old implementation did much more.

For example, it build a list of the missing services on this project. This whole process took about 750ms each time. The current implementation is expected to perform 10x better, as it only searches in the current projects services. Given the service has to be configured anyway, this can be done.
