fixes#6303
BREAKING CHANGE:
For static content projection, elements with *-directives are now matched against the element itself vs the template before.
<p *ngIf="condition" foo></p>
Before:
// Use the implicit template for projection
<ng-content select="template"></ng-content>
After:
// Use the actual element for projection
<ng-content select="p[foo]"></ng-content>
