Endless spinner in `Compute how earnings affect you` when toggling `bi_agi_limit_in_effect`

[MaxGhenis]

In #962 I added bi_agi_limit_in_effect. When flipping it, the population impacts and the net income table work properly, but the Compute how earnings affect you creates an endless spinner.

For example, clicking that button on this reform with a default household produces the error: https://policyengine.org/us/household?older_adult_bi=1000&bi_agi_limit_in_effect=1&bi_agi_limit_amount_SINGLE=50000

That graph works fine with other policies.

I suspect this is also fixed by #966 : will close if so.

966 fixed #964 but this is still broken

Thanks @nikhilwoodruff! Shows this now.
