Add LMDB error string to database transaction exception message
When throwing an exception from being unable to begin an LMDB transaction, include the reason. It's often been due to a write transaction attempted within a write transaction (batch mode), but there can be other reasons such as write transaction attempted while database was opened read only, or environment's map needs to be resized.
