htlcswitch/decayedlog_test: create unique test dbs

Browse Source 
This commit changes the decayed log tests to create
a new temporary database for each test. Previously, all
instances referenced the same db path. Since the tests
are run in parallel, the tests would create/delete the
shared db out from under each other, causing flakes in
the unit tests.
