Fix token drop down on cart check out when numbers are very small

[laurenluz]

Problem

On the cart checkout page, non-zero but small token balances are showing up as 0 in the token list drop down:

Solution

We should make any non-zero number that rounds to less than 0.00 show up as <0.00.

Acceptance Criteria

• Token balances of 0 should show up as 0.00
• Non-zero token balances that round to less than 0.00, show up as <0.00
• Token balances of over 0.00 show up as rounded to the nearest hundredth (e.g. 0.02)
