First half of whitebox_crash_test to keep crashing the same DB

Browse Source 
Summary: Currently, whitebox crash test is not really executed, because the DB is destroyed after each crash. With this fix, in the first half of the time, DB will keep opening the crashed DB and continue from there.

Test Plan: "make whitebox_crash_test" and see the same DB keeps crashing and being reopened.
