fix: Update conditions and unify calculations for the number of "winners" to skip when mixing (#5532)

Browse Source 
## Issue being fixed or feature implemented
`JoinExistingQueue` was tweaked for regtest/devnets in #4394 but we have
"skipping winners" logic in `StartNewQueue` too. We should also use
weighted count when checking "skip winners" conditions.

## What was done?
Add a helper to calculate the number and use it in both methods. Adjust
logic.

## How Has This Been Tested?
Running a local mixing node on devnet ~- no "skipping winners" in logs
anymore.~ and testnet

## Breaking Changes
n/a
