title: Ngx-quill toolbar customization not working - quill Cannot import modules
body: <p>UPDATE: I bailed ship when I realized PrimeNg had a quill implementation and I was already using PrimeNg. Wasn't working at first but upgrading to angular 7 and ngrx 7 beta fixed issues. <a href="https://www.primefaces.org/primeng/#/editor" rel="nofollow noreferrer">https://www.primefaces.org/primeng/#/editor</a></p>
  
  <p>I'm attempting the setup the ngx-quill text editor in my project with a more complete toolbar than the default one. I'm just <a href="https://github.com/KillerCodeMonkey/ngx-quill" rel="nofollow noreferrer">copying this code snippet from the documentation</a> and haven't tweaked (yet!). </p>
  
  <p>I do not get any browser errors if I don't include the modules attribute but I'm wondering if I have an import issue that's only showing when I try to add it?</p>
