Auto merge of #3592 - Eirik0:z-sendmany-better-error, r=bitcartel
Better error message when sending to both sprout and sapling When trying to send to both Sprout and Sapling (not currently supported with z_sendmany) we were getting the following error in our operation result: `general exception: boost::bad_get: failed value get using boost::get`. This PR changes this to fail with a better error message before the async operation begins: ``` error code: -8 error message: Cannot send to both Sprout and Sapling addresses using z_sendmany ```
