Update TDD system for renamed func TRIBITS_UPDATE_GIT_EXTRAREPO() (#130)

I forgot to update the TDD system for my changes for #130.  Since the TDD
system is not under automated testing, this was allowed to be pushed.  I was
slopping in not finding this reference to the old function name.  Sloppy on my
part.
