[ComboBox] `valueChange` is fired twice, when dialog is opened in the callback.

[ipeshev]

Describe the bug 'valueChange' event is fired twice, if а dialog is opened in the callback through service.

To Reproduce

1. Open https://stackblitz.com/edit/angular-wyggzu-mnqcdk?file=app%2Fapp.component.ts
2. Try to change value of the combo - valueChanged logged twice
3. Comment row 55 and try again - valueChanged logged once

Same example would work fine when kendo-dropdownslist is used instead
