repl: pass objectGroup to Runtime.awaitPromise

When the inspector-backed REPL evaluates a promise-returning
expression, Runtime.evaluate stores the remote promise object in an
objectGroup.

Runtime.awaitPromise did not pass objectGroup. Under GC pressure,
the remote promise object could be collected before the await
completed, causing the inspector to report:

  -32000: Promise was collected

This surfaced in the REPL as ERR_INSPECTOR_COMMAND instead of the
user's original exception.

Pass objectGroup to Runtime.awaitPromise so the promise remains
retained until the await completes.
