PollyMC using the default Qt system icons instead of the built-in ones on startup

[FixxAlish]

Operating System

Linux

Version of PollyMC

PollyMC 7.1

Version of Qt

Qt 5.12.8

Description of bug

When launching the app, it uses the default system icons (or none at all if there is no icon for the UI element).

It can be fixed by switching icons or colors in the settings to other options and then back to its original setting.

The problem disappears until you relaunch the app, then the same problem occurs. Using Linux Mint 20.3

Steps to reproduce

• Launch the app
• It uses Linux Mint system icons instead of ones that come with PollyMC

Suspected cause

Something to do with the way that the path to icons is set at startup?

Seems like the same issue as https://github.com/fn2006/PollyMC/issues/19 and https://github.com/PolyMC/PolyMC/issues/1009, they both solved it by updating from Mint 20.3 to 21.
