Toast sample - 'mail' is displayed as text instead of icon

[MonikaKirkova]

Auto Hide section in the Toast topic the third toast in the sample ‘mail’ is displayed as text and not as icon.

Also can we do something about the UI of this sample? It doesn't look very good. Buttons are too close to each other, there is no space or any particular order between them. Same goes for the position and size of the text above each button group. Same goes for this sample: https://staging.infragistics.com/angular-demos/notifications/snackbar-sample-2

This should be resolved once IgniteUI/igniteui-angular#16760 is fixed.
