Fix TestERP5Administration.test_01_RunCheckStockTableAlarm

The test randomly failed since it was created because of low resolution of
creation_date column (in catalog table): Alarm.getLastActiveProcess failed
when the 2 last active processes were created in the same second.

This commit is a hack that relies on the fact that a new Active Process always
has an ID higher than previously created Active Processes.
