Anchor absent in the index

[nicbus]

Using our regtest sandbox and a patched rgb-contracts I am seeing the following validation warning on all rgb accept invocations and on all rgb validate invocations, except for the call to validate during the first trasfer after issuance (but then rgb accept shows the warning):

anchor for operation 9cd...bdb is not found in the index
