Fix: Don't resave the transaction itself

[GalRogozinski]

Description

While rescanning the DB we are not suppose to re-save the existing transactions themselves.
Unfortunately it seems like we were re-saving the transactions and dropping the TAG data itself.

Type of change

• Bug fix (a non-breaking change which fixes an issue)

How Has This Been Tested?

Currently I am rescanning a node. I will validate that Tag information is present before merging.
Complete regression test should be done seperatly in #1466
