fix: version-service should not use process.nextTick (#6124)

Browse Source 
In the beginning we used process.nextTick() as a trick to load some data
initally in the constructor of a service.

This is a bad pattern and we should generally avoid any async operations
in the constructor. Today we have two alternatives:

1. Defer loading until data is needed (wrap it in async)
2. Use the schdule-service.
