Fix DynamoDbLockRegistry.tryLock for "fair" time

Since we don't have choice and wait at minimum `leaseDuration` to be
able to iterate in the Amazon LockClient at least two times and that is
going to be just a contract of this client, so we need to add up a
`timeout` for the `tryLock` to that `leaseDuration`
