test: add reset_chainstate parameter for snapshot unittests

Browse Source 
This CreateAndActivateUTXOSnapshot parameter is necessary once we
perform snapshot completion within ABC, since the existing UpdateTip
test will fail because the IBD chain that has generated the snapshot
will exceed the base of the snapshot.

Being able to test snapshots being loaded into a mostly-uninitialized
datadir allows for more realistic unittest scenarios.
