[Development] 5.5 CI having problems on tst_qmimedatabase-xml

[Hausmann Simon]

Right, in 5.5 any stale state on the file system is likely to survive. In dev (new ci) that problem is gone.

That was it.

Before the change above, integration had failed due to tst_qmimedatabase-xml
and/or tst_qfileinfo in 6 out of the 9 previous integration failures (two
others were unrelated flaky tests).

The CI passed integration on the first attempt with the change above when it
compiled.

So we now know that C:\temp is not getting cleaned in CI machines.
