*** Please remove the following help text before submitting: ***
Provide a general summary of your changes in the Title above
Pull requests without a rationale and clear improvement may be closed
immediately.
Please provide clear motivation for your patch and explain how it
improves
Dash Core user experience or Dash Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always
welcome.
* All other changes should have accompanying unit tests (see
`src/test/`) or
functional tests (see `test/`). Contributors should note which tests
cover
modified code. If no tests exist for a region of modified code, new
tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or
an
explanation of the potential issue as well as reasoning for the way the
bug
was fixed.
* Features are welcome, but might be rejected due to design or scope
issues.
If a feature is based on a lot of dependencies, contributors should
first
consider building the system outside of Dash Core, if possible.

## Issue being fixed or feature implemented
<!--- Why is this change required? What problem does it solve? -->
<!--- If it fixes an open issue, please link to the issue here. -->
Before this fix, uniqueness of HPMN `platformNodeID` was checked only
while processing a block containing a `ProRegTx` or a `ProUpServTx`.
This is not enough as a `ProRegTx` or `ProUpServTx` containing duplicate
HPMN `platformNodeID` must be rejected at tx broadcast level.
## What was done?
<!--- Describe your changes in detail -->
Checking uniqueness when calling respective RPC and when receiving such
txs.

## Issue being fixed or feature implemented
`CDeterministicMNList` stores internally a map containing the hashes of
all properties that needed to be unique.
`pubKeyOperator` don't differ between the two schemes (legacy and
basic(v19)) but their serialisation do: hence their hash.
Because this internal map stores only hashes, then we need to
re-calculate hashes and repopulate.
So when we tried to revoke a masternode after the fork, the `ProUpRevTx`
couldn't be mined because the hash of the `pubKeyOperator` differed.
## What was done?
When retrieving a `CDeterministicMNList` for a given block, if v19 is
active for that block, then we repopulate the internal map.
## How Has This Been Tested?
Without this fix, `feature_dip3_v19.py` is failing with
`failed-calc-cb-mnmerkleroot` (Error encountered on Testnet)
