Fix propagation of async hook ids through callbacks

[alexanderfloh]

Use Call instead of MakeCallback in order to retain the correct async-id through callbacks.

This is also recommended in the Node.js documentation:

Note it is not necessary to use napi_make_callback from within a napi_async_complete_callback; in that situation the callback's async context has already been set up, so a direct call to napi_call_function is sufficient and appropriate.
