Smooth shutdown when an exception occurs during service initialization

[dotta]

This is a development environment issue that occurs when an exception is thrown when the service is created (but not yet started). For instance, if one forgets to enable the Module class (in the application.conf) that binds a service interface to its implementation. Another occurrence of the same problem is when the port assigned to the service is already in use. The issue is particularly annoying when using the runAll task, as the service that is not being started is likely the one a user is working on.
