Recurring tipping still occurs when Rewards are toggled off

[NejcZdovc]

Description

If you turn off Rewards via the toggle at the top of brave://rewards page, Recurring tipping can still occur if the table has sites in it. When Rewards are turned off, monthly tipping should not happen.

Steps to Reproduce

1. Launch Brave with a fresh profile and --rewards=reconcile-interval=15(or a shorter amount of minutes if you can work quickly)
2. Enable Rewards
3. Fund your wallet, verify amount displays in browser.
4. Visit some sites and add them to monthly list
5. Turn off Rewards with toggle at the top of brave://rewards page
6. Wait until the reconcile-interval time is met.

Actual result:

contribution happens

Expected result:

contribution shouldn't happen

Reproduces how often:

Brave version (brave://version info)

Reproducible on current release:

• Does it reproduce on brave-browser dev/beta builds?

Website problems only:

• Does the issue resolve itself when disabling Brave Shields?
• Is the issue reproducible on the latest version of Chrome?
