mobx-react v9 upgrade

[YuHsuan-Hwang]

mobx-react v7 to v9 introduces a breaking change that will require large changes. Computed values and reactions no longer response to (and accept) react states and props. Looks like we will need to create observable copies for all props that are used in computed values and reactions, which could be a huge work.
