component.Base: needsParentUpdate() => add all the resolvers of a client cmp

Clearly an edge case, but the following comes to mind:

• A Component gets an promiseUpdate() call while it is updating.
• It stores resolve inside its own cache
• Once the update cycle is done, it tries to run the next cycle, but a parent is already scheduled
• So, passing the cached resolve fn(s) to the parent cache seems logic
