Fix request body for compute unshelve action API

Compute unshelve action API accept request body with
action name and null value. For exmaple: {'unshelve': null}.
But Tempest pass the empty dict instead of null- {'unshelve': {}}.
This works fine till 2.77 microversionbut after that nova
started rejecting the empty dict {}.

Defaulting the request body to None so that it works for older
as well newer microversion.

Closes-Bug: #1836187
