fix(consensus)!: dont send duplicate substate values when pledging (#…

…1237) Description --- fix(consensus)!: dont send duplicate substate values when pledging Motivation and Context --- When a foreign node pledges the same value (read lock) the contents of the substate were duplicated many times for each transaction. This PR normalises the BlockPledge struct. How Has This Been Tested? --- Existing tests and manually What process can a PR reviewer use to test or verify this change? --- Works as before Breaking Changes --- - [ ] None - [ ] Requires data directory to be deleted - [x] Other - Please specify BREAKING CHANGES: wire protocol breaking change
