Changing options.readOnly doesn't enable/disable quill

[damianaiamad]

The problem is here:

 ngOnChanges(changes: SimpleChanges) {
    if (changes['readOnly'] && this.quillEditor) {
      this.quillEditor.enable(!changes['readOnly'].currentValue);
    }
  }

This solution works for me:

  ngOnChanges(changes: SimpleChanges) {
    if (!changes.options || changes.options.firstChange || !this.quillEditor)
      return

    this.quillEditor.enable(!changes.options.currentValue.readOnly);
  }

it might be safer to directly use quill's isEnabled function here to check, not sure how tightly aligned the readOnly value is with the enabled/disabled state
