Crucial fix for the UTXO difference mechanism (#2114)
* Illustrate the bug through prints

* Change consensus API to a single ResolveVirtual call

* nil changeset is not expected when err=nil

* Fixes a deep bug in the resolve virtual process

* Be more defensive at resolving virtual when adding a block

* When finally resolved, set virtual parents properly

* Return nil changeset when nothing happened

* Make sure the block at the split point is reversed to new chain as well

* bump to version 0.12.4

* Avoid locking consensus twice in the common case of adding block with updateVirtual=true

* check err

* Parents must be picked first before set as virtual parents

* Keep the flag for tracking virtual state, since tip sorting perf is high with many tips

* Improve and clarify resolve virtual tests

* Addressing minor review comments

* Fixed a bug in the reported virtual changeset, and modified the test to verify it

* Addressing review comments
