Previously, we call the JS land `runNextTicks` implementation immediately from JS land after evaluating the main module or the input, so these synchronous JS call frames would show up in the stack trace of the async errors, which can be confusing. This patch moves those calls into C++ so that more of these internal scheduler implementation details can be hidden and the users can see a cleaner a cleaner async JS stack trace.
