Do not remove all coins with the same contract id unless the chain ids match

Description

When removing assets via the visible assets modal, multipole coins may be removed if the contract addresses are the same. We should also check that the chain ids match before removing assets.

Steps to Reproduce

1. Add 2 tokens to the wallet with the same contract address, but different chain ids
2. open visible assets modal
3. remove on the tokens

Actual result:

Both tokens are removed

Expected result:

only the selected token should be removed
