[PlacesItemModelTest] Try to double test timeout
The randomly failing testRefresh() on the CI can be reproduced by
replacing the QTRY_COMPARE with a simple QCOMPARE.
So it seems the CI can be slow such that the default QTR_COMPARE
timeout of 5 seconds is not enough.
If a timeout of 10 seconds fixes this particular test case, we can use
this bigger timeout also in the other failing tests.
