[Bug]: Transactions - Pending transactions add up transactions with same nonce (speed up/cancel)

[seaona]

Describe the bug

Whenever I am performing a tx when I have another one pending, I can see the Information display saying I have a pending tx. However, if I have speed up/cancelled that transaction I see how the number of pending transactions increases, even though the speed up/cancel tx's all have the same nonce, meaning just 1 is actually pending

Expected behavior

Possibly transactions with the same nonce should count as 1 pending tx instead of adding up to the queue? Similarly as what we do in the Activity list (all same nonce tx's are consolidated into 1)

Steps to reproduce

1. Start a tx with low nonce
2. Trigger speed up/cancel several times
3. Start a new tx
4. See as many pending tx's as performed in step n1 + n2
