[BUG] overmind-statechart throws error when react fash refresh kicks in

[schiller-manuel]

React's fast refresh reruns statechart when a module that contains this call is edited.
As the statechart is already initialized, a config error is thrown since states and matches are already present in the current state.

These are the affected lines:

 if (config.state && (config.state as any).states) {
    throw new Error(
      `Overmind statecharts: You have already defined the state "states" in your configuration. Statecharts needs this, please rename it`
    )
  }

  if (config.state && (config.state as any).matches) {
    throw new Error(
      `Overmind statecharts: You have already defined the state "matches" in your configuration. Statecharts needs this, please rename it`
    )
  }
