fix!: replay issue when round is 0 on replay.

[QuantumExplorer]

Issue being fixed or feature implemented

There were a few pretty bad issues fixed in this PR.
First there were issues when reenabling withdrawal keys.
There were also issues when dealing with complex situations around operator identity changes.
But the most important fix is that we can now rollback to the transaction savepoint properly. Without this multiple rounds at genesis would crash the system.

What was done?

Updated to GroveDB v2.0.3
Added many tests.
A lot of fixes in Masternode identity updates.

How Has This Been Tested?
