[bugfix] block non native rune being sent out of the network

It was observed that a couple wallets were arb'ing via BEP2 rune. This shouldn't be allowed as it can mess with the circulating supply of native rune. Right now, the network has more native rune in it then it should, making it "over solvent". The network just needs to burn that additional native rune and block people from arbing via BEP2 rune again.
