Fix Accept States for Group Match Tests

[Divide-By-0]

In some regex, such as 1=(a|b) (2=(b|c)+ )+, which doesn't have other characters appended the last group, the generated circuit seems no able to properly calculate the data points. But when it has something appended, such as 1=(a|b) (2=(b|c)+ )+d, it works as expected. For now, I reckon this is an issue originating from the lexical.js.
