Adding an Element causes WM to hang

[HashimHS]

The World Model gets stuck when using 'add_element' method within a skill. For example:

class primitive_skill(PrimitiveBase):
...
def run():
object_pose = PoseStamped()
element_pose = Element("skiros:TransformationPose", elabel='object_pose')
element_pose.setData(":PoseStampedMsg", object_pose)
self._wmi.add_element(element_pose)
...

But when specifically setting:

self._wmi._allow_spinning = True

The issue is resolved.
