Transaction list show all transactions regardless of active network

[Radosław Szpiech]

Description

All transactions for all networks are visible, which is against ACs in #488: If I switch network, transactions list changes to show the transactions for that network. If we made multiple transactions using different networks during one session, all of them are visible on transaction list. That causes errors when we want to track specific transaction in block explorer.

Steps to Reproduce

1. Create few transactions using fairground network
2. Create few transactions using stagnet1 network (or any other than fairground)
3. Open transaction list -> All transactions from both networks are visible.
4. Open transaction that was made using fairground network, click explorer link -> transaction is not found in explorer as it redirects to stagnet1 explorer looking for fairground transaction.

Expected behavior

Transaction list should contain transactions made during single session and current network only.
