findLikelyTokens didn't return the tokens minted with rainbow bridge

[think-in-universe]

Description

findLikelyTokens() should be able to return the tokens minted by rainbow bridge, but it seems it doesn't work.

Steps to reproduce

On testnet:

1. Mint some tokens via rainbow bridge (ERC20 to NEP141), e.g. https://explorer.testnet.near.org/transactions/2E2Xco24GmjbzVdJRaSbBw4nqZ27pc8iQgMDmUXbmaBg to an account

2. Open the wallet page https://wallet.testnet.near.org/ and the NEP141 token is not listed.
