SF-3497 Fix no Lynx overlay when Lynx problems panel nav to another chapter

[siltomato]

This PR fixes an issue where the lynx overlay would not display when using the lynx problems panel to navigate to (and display the overlay for) an insight from a different chapter.

The fix involved waiting for the insights for the chapter to render before making the call to render the overlay.

Just one very minor nit in a .spec.ts file, so I will approve so to not hold up testing.

src/SIL.XForge.Scripture/ClientApp/src/app/translate/editor/lynx/insights/lynx-insight-editor-objects/lynx-insight-editor-objects.component.spec.ts line 5 at r1 (raw file):

import { Delta } from 'quill';
import { BehaviorSubject } from 'rxjs';
import { TextDocId } from 'src/app/core/models/text-doc';

NIT: This should be:

import { TextDocId } from '../../../../../core/models/text-doc';

(I also noticed this in \src\SIL.XForge.Scripture\ClientApp\src\app\translate\editor\lynx\insights\lynx-insight-overlay\lynx-insight-overlay.component.spec.ts)

Code quote:

import { TextDocId } from 'src/app/core/models/text-doc';
