Cannot close pool after calling any indy_vdr_pool_... function

[berendsliedrecht]

When writing tests for the new NodeJS wrapper I encountered some issue with pool_close(). The issue is that when I create a pool and immediately close it nothing goes wrong, however when I create a pool, get the verifiers and close the pool I never receive write access via the lock. I am supposed to call a free or drop or something else after acquiring the lock (I assume this is handled rust via drop but I am not too sure)?
