Issue Description:

• Currently while showing tokens in wallet, we consider ticker to be unique
• Using the ticker, we group the balance across chains
• But that's not true and there might be collisions, when two tokens have same ticker.
• This will lead to incorrect grouping
• In the past, we removed these colliding tokens manually
• But with auto refresh tokens lists, this manual process has been removed
• We need to update the logic on the client side to group by name, which is truly unique, not ticker

Acceptance Criteria:

The change is not visual, so hard to test.

• The token grouping logic is updated to group by token name instead of ticker

Notes:

• @saledjenic is handling this on Desktop side, in case help is needed
