Context Providers are unnecessary runned on checkout -> select payment page

[arti0090]

I saw when debugging that on Checkout->select payment Context Providers: RegulationsUrlContextProvider and BankListContextProvider are ran unnecessary.
We could investigate why does it happens cause it might impact performance of the feature.
On my last try they ran:

• BankListContextProvider 10 times (it has calls to API (cached) and DB inside)
• RegulationsUrlContextProvider 50+ times 😱

Steps to reproduce:

• create order with any shipment and total more than 0.01
• go to select payment page
• on any of these providers 'provide' function put a breakpoint and count 🙃

I believe the BankListContextProvider was optimized to fetch channels only with PBL, but this was removed here: https://github.com/CommerceWeavers/SyliusTpayPlugin/pull/100/files#diff-a7732c1da78e6bf7b920a5cdd30d6ee2f05628fb2325312afa92fca439902a41L36 🤔
