clear ping history before starting check

Another scenario where the TestHealthCheckScheduler could fail
was when taking 50 sessions from the pool would take so long
that the first sessions taken from the pool would already have
exceeded the maximum number of pings wanted in the test, or
would exceed this number before the last session would reach
the minimum. The ping history is therefore now cleared before
starting the waitFor(...) method.

Fixes #1491
