This allows to defer the toString() invocation until it is really
needed, and so allows to speed-up the test execution.
I was testing a release shared developer build, running
tst_QStringApiSymmetry 10 times before the change, and 10 times after
the change, and then taking the average execution duration, as
reported in the log.
Before the change (using QCOMPARE): 51ms
After the change (using QCOMPARE_EQ): 45ms
As we see from the results, the benefit is around 10%.
