Nate Bosch f065dca391 Avoid permanently paused isolates
These tests have some exceptions caused by missing fields on the
dynamic variable. The exceptions cause the `isolate.resume()` call to
not run, which also cause the test body to not complete.

Currently this is masked by the test runner, which immediately ignores
the test body once the first error occurs. That behavior is changing,
and a failure will not immediately end a test when the body is still
running. https://github.com/dart-lang/test/pull/1815

Some of these tests are currently are expected to fail, but not to
timeout. Fix the test implementations to more reliably complete the test
body, even when the test had an error. This does not fix the tests
themselves, it maintains the current pattern of failure, even after
updating the test runner.

- Use `Stream.firstWhere` over cancelling the stream subscription after
  the first breakpoint.
- Use `Future.whenComplete` to ensure the isolate is always unpaused,
  including after an exception in the expectations.

Tested: Passes with updated test runner in https://dart-review.googlesource.com/c/sdk/+/275401/4

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
