Prepare terrain for reuse of pseudo
Similarly to account / accountRemoved we should have name / nameRemoved in case of pseudo is freed blockchain side and made available for a reuse. That means the pseudo would be a unique identifier, but only at a given moment in time.
- Alice confirms identity with pseudo "Alice"
- Alice identity is deleted, "Alice" pseudo is made available again
- Bob confirms identity with pseudo "Alice"
In this case, indexer entry for Alice identity should have status "Removed" (does not exist on blockchain), null name (or alternative), and nameRemoved equal to "Alice". Bob should have name equal to "Alice" and nameRemoved null.
