test(dart/transform): Update dependencies & fix Dart tests

Widen version dependencies for `package:angular`, `package:code_transformers`,
and `package:observe`.

`package:guinness` uses `package:unittest` while
the newest versions of `package:code_transformers` use `package:test`.
This causes our end-to-end Dart transformer tests (which use testing
code in `package:code_transformers`) to be skipped.

To fix this:
- Move e2e tests to run in a separate file
- Run `gulp test.server.dart` tests serially

Closes #5922

Closes #5935
