Subject: [PATCH] test sweep: cover base/disposable.dart (T-91)

Three pure-Dart tests covering the Disposable mixin: the disposed
getter flipping after dispose(), onDisposed firing once, and
register propagating dispose to child disposables.

Coverage: disposable.dart 12/17 -> 17/17. Total 71.20% -> 71.23%.
