We should pump one frame at app startup even if the screen is off #165

Originally opened as https://github.com/flutter/engine/issues/1206
Authors are rarely going to test their apps with the screen off, but if we don't pump their app with the screen off, their App widget isn't going to be synced, their RenderObject tree isn't going to be laid out, and so forth, so if they try to do anything using the tree, it'll fail.
So we should either pump one frame to ensure that the app is always more or less in the same state, or we should document patterns and anti-patterns for how to do things that depend on app state and render tree layout, e.g. don't use a timer but use an animation frame callback, etc.
