[BUG] Cannot parse import .html files

[joefiorini]

Overview of the issue

This is the same problem as in #921, #317, #1018, #637, namely, all of our components directly import html templates as strings rather than using the templateUrl property (we are NOT using angular-cli). A failing component looks like the following:

example.component.ts

import { Input, Component } from '@angular/core'

import template from './example.component.html'

@Component({
  selector: 'example',
  template,
})
export class ExampleComponent {
}
