fix: Let CDeterministicMN::ToJson() return correct collateralAddress for spent collaterals (#5607)

Browse Source 
## Issue being fixed or feature implemented
Historical masternode data returned via rpcs like `protx listdiff` can
be broken because some collaterals might be spent already and
`GetUTXOCoin` wasn't able to get any info.

## What was done?
Use `GetTransaction` as a fallback.

## How Has This Been Tested?
run tests

## Breaking Changes
n/a
