fix(@schematics/angular): fix extra comma if inlineStyle is on

Chau Tran · Keen Yee Liau · commit f089bb144c5c · 2020-03-30T10:22:37.000-07:00
When generating a new component, if `inlineStyle` and either
`viewEncapsulation` or `changeDetection` flag is provided, there is an
extra comma after `styles: [],,` causing the component to bugged out.
