[bug]: tapcli assets mint finalize returns "new_grouped_asset": false for new grouped asset

[gijswijs]

Background

When minting a new grouped asset, the initial minting command returns the asset inside the pending_batch with "new_grouped_asset": true but upon finalizing the batch the asset is identified as being not a new grouped asset ( "new_grouped_asset": false)

Your environment

• lnd v0.18.4-beta
• tapd v0.5.0-alpha
• bitcoind v28.0

Steps to reproduce

tap@alice-tap:/$ tapcli assets mint --type normal --name florin1 --supply 1000000 --decimal_display 3 --meta_b
ytes '{"hello":true}' --meta_type json --new_grouped_asset
