clazy build/tests fail with Qt 5.15.8 - succeed with 5.15.7

STEPS TO REPRODUCE
1.  Build clazy in Ubuntu or Debian development versions with Qt 5.15.8 running tests; 
OR run autopkgtests on Debian or Ubuntu CI infra with Qt 5.15.8
OR build clazy on KDE Neon with their Qt 5.15.8 and tests enabled (Ubuntu 22.04 LTS base and toolchain)
