check if assetQuantity is None. If so, don't caculate the security.

First of all, thank you for the amazing work!

Found a little kinda extreme case here.. when having an upcoming recurring buy transaction, the assesQuantity might be None.

Traceback (most recent call last):

Therefore, added a check before generating the description field..
