Bug 10499: VirtualShelves.t - wrap tests in a database transaction

Before this patch, the queries in VirtualShelves.t were committed in the
database and have to be removed at the end.

This patch wraps tests in a database transaction.

Test plan:
prove t/db_dependent/VirtualShelves.t
VirtualShelves.t .. ok
All tests successful.
Files=1, Tests=72,  1 wallclock secs ( 0.06 usr  0.00 sys +  0.72 cusr  0.06 csys =  0.84 CPU)
Result: PASS
