Ticket #48226 - CI test: fixing test case for ticket 48226

Description: commit f5d24450477f8341261c3e5cb5c54ec1ab83328f had an
issue in valgrind check.  The script calls valgrind_check_leak twice,
in which the server is stopped.  Before calling the second valgrind_
check_leak, the server (master 2) has to be restarted.  Also, "Invalid"
is reported after another server (master 1) is restarted.  To capture
it, start master 1 before calling the second valgrind_check_leak.
