Workbench.{Service} doesn't call Initialize

[bruno-brant]

Workbench seems to be responsible for calling Initialize on each service it provides, as it can be seen from the method GetRegisteredService:

However, for some reason, there's a very similar method called GetService that doesn't call initialization, and that method is the one used by the public static properties like Telemetry, Repository, etc.

This can lead to some bugs.
