Chosen icon is not displayed in popup with `notify-send` from Terminal

[lukors]

Prerequisites

• [x] I have searched open and closed issues for duplicates.

Describe the bug

When I run for instance notify-send --icon=address-book-new "My notification" in Terminal with an icon specified, the popup that appears has a generic "info" icon.

However, if I then go to the notification popover the correct icon is shown.

To Reproduce

Steps to reproduce the behavior:

1. Open up a Terminal window
2. Write notify-send --icon=address-book-new "My notification"
3. Look at the icon of the notification that pops up
4. Open up the notification popover and look at the notification's icon there

Expected behavior

The specified icon should be displayed in both places.
