App icons are displayed in full colour instead of symbolic in v83 #410

Describe the bug
After updating to v83 the app icons in the App Menu are displayed in full colour instead of symbolic and they are glued to the start of the app title.

To Reproduce
Steps to reproduce the behavior:

1. Enable the Application Menu in the Unite extension settings.
2. Make sure the Disable Icon option is not enabled.
3. See the full-colour icon beside the app name, without any spacing,

Expected behavior
The app icon should be symbolic and should have a space between it and the app/windows title.
