binding: navigation: move get_storage_from_value call within write lockicefish_8.99.2icefish/8.99.28.99.2
json_object returned from get_storage_from_value() needs to be protected
within the write lock. This is to prevent reentrant calls to broadcast() from
accessing it, and running json_object_put()
