Title: Feature/finish requires existing tag pointing to head

This is my reimplementation of petervanderdoes/gitflow#18 and petervanderdoes/gitflow#19 using `git_compare_branches()`

During a finish when tagging is enabled, if the tag already exists, it must "point" to the branch HEAD.

Today, the tags are creating after merging to the production release branch, this mean that the second parent of the tag must point to the current HEAD.
