[Bug] System Tray icon scaling option doesn't work on initial startup

[EbonJaeger]

Description

When first starting the system, the system tray items all act as if scaling is enabled, even though the option is set to disabled in Budgie Desktop Settings. The setting has to be toggled on and off again for it to not scale the icons.

Budgie version

budgie-desktop 10.8 (git-b3b67fd96b2455d665aa960c950f24259d6b3547)

Operating System

Solus 4.4 Harmony

Steps to reproduce the issue

1. Log in to the desktop
2. Notice tray icons are large
3. Open Budgie Desktop Settings
4. Go to system tray settings
5. Notice the option to enable scaling is off

Actual result

Tray items have their icons scaled.

Expected result

Tray items should not have their icons scaled.

Additional information

This is occuring for me on my Windowing/Icon Tasklist branch which was rebased to main after the option was added.
