* moved Dependency.Stop() logic into Service.Stop().
* return Stop() errors for all dependencies, not just the first one.
* removed unneeded TestStopDependency() & TestIntegrationStopDependency() tests.

why did you remove the mutex here ? I'm not really sure why we had one in the first place maybe to fix some strange behaviors with docker when we stop containers or something like that

That mutex was there to prevent concurrent writes to err. But with the updated version, it's handled inside errs.Append().

service: fix stop order between service & dependencies
91b3509 
this bug was introduced by #884.

service itself should always be stopped first to give it a chance to properly shutdown itself. if depencies were stopped first, service may try to reconnect them or may start some fault toleration protocols for no reason.
