WFLY-2502 Naming context read-only during RA stop

When the `ResourceAdapter#stop()` method is invoked on an annotation
based 1.6 JCR resource adapter the naming context is read only. The
method can be invoked in two cases. Either a normal undeployment or
a clean up after a failed deployment.

 - `AbstractResourceAdapterDeploymentService#stopAsync` pushes the owner
 - `AbstractResourceAdapterDeploymentService#unregisterAll` catches any
   error that `ResourceAdapter#stop` may throw and logs it
 - `AbstractResourceAdapterDeploymentService#cleanupStartAsync` also
   pushes the owner
