"Sadly, no tokens yet" after importing wallet with non-zero balance

[garrettr]

Description

After importing a funded Brave Payments wallet into Brave Rewards, the Rewards Settings page shows the correct non-zero balance for the wallet, but continues to show the "Sadly, no tokens yet" sidebar. This is confusing because it contradicts the existence of the tokens from the imported wallet, which are reflected in the displayed non-zero wallet balance.

Test plan / Steps to Reproduce

1. Import Muon/Brave Payments wallet into b-c/Brave Rewards (detailed test plan in Import Brave Payments data from Muon brave-core#736).
2. Click Brave Rewards icon in address bar, then Rewards Settings in the dropdown.

Actual result:

Expected result:

If the wallet balance is zero, the sidebar should not say "no tokens yet."
