Ads toggle turned on when updated to 0.60.14

[LaurenWags]

Description

When I updated my personal Dev profile from 0.60.13 to 0.60.14, Ads became enabled on 0.60.14. That should not have happened. Ads were off (per UI toggle on 0.60.13) but on 0.60.14 Ads UI toggle switched to on.

This did not reproduce with a clean profile. Meaning, clean profile with 0.60.13, enable rewards, toggle Ads off. Update to 0.60.14 and Ads toggle was still off.

Steps to Reproduce

1. Have a Dev profile with Rewards enabled that you've used for several versions.
2. Verify Ads toggle is off on 0.60.13.
3. Update to 0.60.14

Actual result:

Your Ads toggle may be switched on.

Expected result:

Ads toggle should be off.

Reproduces how often:

Unsure, I only have been able to reproduce with my personal profile.

@LaurenWags @NejcZdovc @jasonrsadler @ryanml is this happening on 59.x?

[LaurenWags]

@rebron iirc this didn't happen all the time (@ryanml had a very tough time reproducing).

@rebron @LaurenWags I know what the problem is and I will fix it
