Generated widgets don't make use of relevant default exports

[sbinge]

Enhancement

Widgets created via dojo create widget don't import appropriate default exports as defaults, for exampleWidgetBase.

Package Version: 5.0.0

dojo create widget --name MyComponentWidget --component

Expected behavior:

import { DNode } from '@dojo/framework/widget-core/interfaces';
import ThemedMixin, { theme } from '@dojo/framework/widget-core/mixins/Themed';
import WidgetBase from '@dojo/framework/widget-core/WidgetBase';

import customElement from '@dojo/framework/widget-core/decorators/customElement';
...

Actual behavior:

import { DNode } from '@dojo/framework/widget-core/interfaces';
import { ThemedMixin, theme } from '@dojo/framework/widget-core/mixins/Themed';
import { WidgetBase } from '@dojo/framework/widget-core/WidgetBase';

import { customElement } from '@dojo/framework/widget-core/decorators/customElement';
...
