Fix automatic version update.
This fixes two things:
1. Guarantee that versions are bumped up also when presubmit errors exists. Those errors originate from other CLs and should not stop the automatic versioning.
2. Calculate the last bleeding edge version when pushing to trunk based on remote branch svn/bleeding_edge and not on local branch master. The master branch is not kept up-to-date by the script.
