[runtime/observatory] Clean up rewind command feedback

This check is also replicated later within [debugger.cc](https://github.com/dart-lang/sdk/blob/master/runtime/vm/debugger.cc#L4098), so it didn't necessarily matter that this check did not work.

Despite this, I think the earlier check does not hurt though, and I
also added feedback for when the supplied argument is not an int
rather than just throwing an error.
