v0.3.1

[sscovil]

This patch fixes an issue where the underlying ERC-1155/ERC-6909 token balances were not being updated when pruning balance records, causing a discrepancy between the balance totals in the token standard contract and those in the TokenEphemeral contract.

This was not a critical issue, since the balanceOf methods in both EVMAuth contracts only called down to the balanceOf method defined in TokenEphemeral; however, we felt it was prudent to ensure that both balances were consistent and that expired tokens were actually being burned.
