add another print trace to runInView (#148337)

In service of flutter/flutter#146879. See flutter/flutter#146879 (comment). I wonder if something is going wrong in the process of subscribing to the isolate event stream in the VM service. This adds a print trace to the `catch` clause of this subscription call.
