fix: adjust GetPaymentsLimit to work correctly with historical blocks, adjust sb params on regtest, tweak tests (#5641)

## Issue being fixed or feature implemented
Noticed a couple of things while I was trying to figure out if an
[issue](https://github.com/dashpay/dash/pull/5627#discussion_r1367153099)
@knst mentioned in #5627 could actually exist:
1. `GetPaymentsLimit()` won't work correctly with historical blocks rn.
We don't use it that way internally but it could be done via rpc and it
should provide correct results.
2. superblock params on regtest are too small to test them properly
3. because of (2) and a huge v20 activation window (comparing to sb
params) `feature_governance.py` doesn't test v20 switching states.
There's also no "sb on v20 activation block" test.

~NOTE: based on #5639 atm~

## What was done?
fix it, pls see individual commits

## How Has This Been Tested?
run tests
