Missing import statement when ember/no-incorrect-computed-macros fixer is run

[dcyriller]

Hello @bmish - wanted to let you know a small bug we noticed.

Running yarn lint:js --fix with the rule ember/no-incorrect-computed-macros enabled on the following:

import Component from '@ember/component';
import { and } from '@ember/object/computed';

export default Component.extend({
  cp: and('another.prop'),
});

the CP gets correctly fixed but not the import statement.
