[Bug]: Restored wallet splits Boosted CPFP transactions into separate activities

[catch-21]

Describe the bug

When boosting a transaction, the existing activity is updated to reflect the change and combines the subtracted amounts. If the wallet is restored the transactions are displayed as separate activities. We should aim to keep the activity list constant after wallet restore.

Reproduce

1. Send onchain funds using a fee rate that needs a boost
2. Boost the transaction
3. Observe the two transactions are combined in one activity
4. Restore the wallet
5. Observe the two transactions each now have their own activity

Screenshots / Recording

In the following example, the final transaction in the CPFP chain is d69eeb99e9a562e7b9a6a34abce3c77808e4e0f8a077058ee1558881ae209a2b

Before restore, two activities are shown for a chain of three transactions. The top one had a boost and so combines two CPFP transactions and the bottom is a single transaction:

After restore there are three activities, one for each transaction in the CPFP chain:
