Some monochrome icons are displayed as non monochrome
# What happens?
If I switch to the monochrome set, the following two items are still colored.
```
<!-- Calendar -->
<item component="ComponentInfo{com.simplemobiletools.calendar.pro/com.simplemobiletools.calendar.pro.activities.SplashActivity.Blue_grey}" drawable="calendar"/>
<!-- Threema -->
<item component="ComponentInfo{ch.threema.app/ch.threema.app.activities.MainActivity}" drawable="threema"/>
```
