Bug fix: Synonym Sync: Remove recapitalization of acronyms (#724)

Bug fix: Synonym Sync: Recapitalization of acronyms
- Fixed bug where this operation was being done for -updated and -confirmed, but it should only be done for -added.
- Bug fix: I don't think we should have ever had this in the first place. I don't see that it actually fixes anything; only should cause bugs.
