Openly Adopt Faith decision issues

[Valikdu]

Decision is secret_religions_openly_adopt_faith. Playing with Steam CK2+ with DLC enabled.

1. Taking the decision still requires 500 society currency, even though there's no society. Taking the decision is possible while being a member of any society and having 500 of its currency.

2. After the decision has been taken, the provinces that have previously had the "prepare ground" decision used on them (and have the "secret [religion] community" province modifier on then) do not flip to the new religion.
