Fixes a NPE if Bus is not registered
Just adding the bundle in an OSGi container causes a NPE in the logs
because the Activator is called, but no Bus service is available. Even if
there's a bundle providing the Bus service it could be registered after the
asyncclient Activator executes so the `HTTPConduitFactory` service will be
registered indeterministically. The changes will wait for the Bus service to
become available and register the `HTTPConduitFactory` service.
Here's the stack trace of the exception:
