SceneManager::findComponents does not work before mainloop has started

[ataulien]

When calling SceneManager::findComponents before the game is acutally running, it will return an empty list, even though there are components of the type it should find in the world.

This is because these three vectors are empty:

Vector<HComponent> mActiveComponents;
Vector<HComponent> mInactiveComponents;
Vector<HComponent> mUninitializedComponents;

They are initialized in SceneManager::processStateChanges, which has not been called at that point, so all components added so far are still stuck in the mStateChanges vector.

A possible workaround is to call setComponentState, which will call processStateChanges internally like so:

bs::gSceneManager().setComponentState(bs::ComponentState::Paused);
bs::gSceneManager().setComponentState(bs::ComponentState::Running);

Then findComponents seems to work fine.
