Resolve the operator user, password and comment before the interop try
blocks, and match ArgumentException as an MXAccess failure only when it
carries E_INVALIDARG and is not ArgumentNullException or
ArgumentOutOfRangeException. A programming error inside the try blocks
now propagates instead of being reported as an authentication or write
failure.
Fixes#164
