Omit lodash.omit

`lodash.omit` is usually used for removing certain props. However, this can be re-written as:
```js
const {
    /* eslint-disable no-unused-vars */
    onDrop,
    dragInfo,
    componentRef,
    /* eslint-enable no-unused-vars */
    ...componentProps
} = this.props;
```

This can reduce amounts of dependencies.

(also `lodash.pick` and `lodash.isequal` is not used anywhere?)
