Drop TimerTest::testStopwatch

(that had been added with 6e13585508ca3c9b66c6571ad1eb42bfcb66ef0b "Add a
TaskStopwatch to interrupt idle loops").  By the same reasoning as in
92e42a0fde32e3f2dbe2c786a0e41547e4912b4b "Drop bogus check from
TimerTest::testStopwatch", there is no guarantee that a StopwatchIdle would run
(close to) ten iterations of Invoke before calling Stop, so the two checks

    CPPUNIT_ASSERT_DOUBLES_EQUAL(10.0, double(n1Iter), 1.1);
    CPPUNIT_ASSERT_DOUBLES_EQUAL(10.0, double(n2Iter), 1.1);

are bogus, too.  And there are reports of failures like
<https://ci.libreoffice.org//job/lo_tb_master_linux/37847/>:

> /home/tdf/lode/jenkins/workspace/lo_tb_master_linux/vcl/qa/cppunit/timer.cxx:603:TimerTest::testStopwatch
> double equality assertion failed
> - Expected: 10
> - Actual  : 6
> - Delta   : 1.1

So remove those two bogus checks.  But with them gone, testStopwatch would be
rather pointless, so remove it completely.
