fix: do not show nonce conflict warning for batch transactions.

[jmealy]

What it solves

Resolves #3502

How this PR fixes it

Displays batch transactions as a single transaction instead of a group of transactions.

How to test it

• Create a batch tx and sign
• Create any other tx and sign
• bulk execute the two Txs
• There should be no warning about conflicting nonces within the bulk tx, as they are all executed as one tx with the same nonce
