Remove dispatch fetchCurrent user action in BasicLayout

[dodo920306]

Since SecurityLayout will fetch the current user, there is no need to fetch the current user again in BasicLayout. As presented in src/dashboard/config/router.config.js:

...
  {
    path: '/',
    component: '../layouts/SecurityLayout',
    routes: [
      {
        path: '/',
        component: '../layouts/BasicLayout',
        authority: ['admin', 'member'],
        routes: [
...

SecurityLayout will always be accessed first before BasicLayout, and we have fetchCurrent in SecurityLayout:

...
  componentDidMount() {
    this.setState({
      isReady: true,
    });
    const { dispatch } = this.props;

    if (dispatch) {
      dispatch({
        type: 'user/fetchCurrent',
      });
    }
  }
...
