Shovel bufixes (backport #14732)

[mergify]

This PR adds a few testcases common to all protocols and some bugfixes:

• Count confirmed messages just once in local shovels
• Auto-delete amqp10 shovels with 0 messages set to transfer
• Reject amqp10 shovels with delete-after and no-ack options set together - same behaviour as 0.9.1 and local shovels
