Prior to this change, a method call of a local template variable would
incorrectly be considered a call to a method on the component class.
For example, this pattern would produce an error:
```
<ng-template let-method>{{ method(1) }}</ng-template>
```
Here, the method call should be targeting the `$implicit` variable on
the template context, not the component class. This commit corrects the
behavior by first resolving methods in the template before falling back
on the component class.
