Build better faked up req_op_context when real one isn't available

Remove req_op_context from state async functions

Many of these functions have no need of a req_op_context.

If one of these functions actually needs a req_op_context it already is
building the best one it can given the information available to it.
There is no sense faking up a root context without an export.
