The discourse-reactions plugin has a rollback function, when the `toggle.json` request fails, the page should rollback the reactions to the original state.

However, the function is broken, and the original `_rollbackState()` function never works as the state itself changes when `toggleReaction` is called. And the reaction state never goes back without refreshing/reloading the window, leading to the heart/reactions leaving on the page even when the request failed.

This commit fixs this by adding a new function `_captureState()`, keeping the state in a const value, and revert it to the page data when necessary.

It was just a flaky spec, I have merged the PR now 🙂
