bug: boosted send shows the old txid and fee #1815

Twin: none (Android only)

What happened

After boosting an on-chain send (RBF), the app reports success before the replacement transaction's activity exists. Opening the send right after shows the original TXID and fee instead of the replacement's.

Expected

The boosted send's activity shows the replacement TXID and its actual fee as soon as Boost reports success, also after successive boosts.

Reproducibility

Often, when opening a send right after boosting it.
