CSS transition polyfill initial state improvement

[necolas]

Adds support for CSS transitions when an element doesn't include transitions in the initial state. This supports the use case where a mounted component is updated to add CSS transition styles. It should be re-rendered as an Animated component instead of printing an error about not having an initial transition state.

The 'useStyleTransition' hook is also moved out of 'createStrictDOMComponent' and into the 'useStyleProps' hook.
