Parsing event fails when event name is non-primitive value

Summary

If first argument to $emit is an object property, the parser does not handle this correctly.

Steps to reproduce

const EVENTS = {
  CLOSE: 'close'
}

export default {
  methods: {
    /**
     * Close modal
     */
    close () {
      /**
       * Emit the `close` event on click
       */
      this.$emit(EVENTS.CLOSE, true)
    }
  }
}

The end result of this rendered via @vuedoc/md is:

• ****unhandled-event-name****

What is the current bug behavior?

The parser does not accept non-primitive values.

What is the expected correct behavior?

The parser accepts non-primitive values.

Possible fixes

A possible solution for this could be to allow specifying a name for the event via JSDoc annotation:

const EVENTS = {
  CLOSE: 'close'
}

export default {
  methods: {
    /**
     * Close modal
     */
    close () {
      /**
       * Emit the `close` event on click
       * @event `close`
       */
      this.$emit(EVENTS.CLOSE, true)
    }
  }
}

Context

My goal here is to be able to export a hash with component events, for use in unit testing.
