Total balance shows negative amount for a new wallet

[srirambv]

Description

Total balance shows negative amount

Steps to Reproduce

1. Build from source and enable Rewards
2. Claim Token grant should add 20 BAT to wallet (currently hardcoded to 10 BAT)
3. Fund wallet with 10 BAT, Total wallet summary should show up as 30 BAT
4. Set monthly budget to 15BAT
5. Rewards summary shows Token Grant as 10 BAT (expected due to hardcoded value), Brave Auto-Contribute shows -10BAT (added funds to wallet), Total shows -5BAT (doesn't make sense considering wallet with added funds and hardcoded grant value should add up to 20BAT and monthly budget is set to 15 BAT)

Actual result:

Monthly budget - 15 BAT
Added Funds - 10BAT
Grant claimed - 20 BAT (hardcoded to 10BAT)

Monthly budget - 10 BAT
Added Funds - 10BAT
Grant claimed - 20 BAT (hardcoded to 10BAT)

Expected result:

Total should only show negative value if the combined value of Added funds + Grant claims is below the monthly budget.
