Tagged CI builds are failing

Problem

Example: https://travis-ci.org/CityOfZion/neo-local/builds/409058230

CI builds on the master branch or a tag should ignore the make check-version check as that should apply to a feature branch.

See:

https://github.com/CityOfZion/neo-local/blob/fb455dbc9a50523ac49a13711324812e40d87507/scripts/travis.sh#L1-L12

@revett upon research I stumbled upon the fact that $TRAVIS_BRANCH is either empty or contains the tag name on tagged builds, which is why the build runs make check-versions.

• https://docs.travis-ci.com/user/environment-variables/#default-environment-variables

Proposal: Use $TRAVIS_TAG instead

Hello? Will this be merged soon? Or at least reviewed? @jeroenptrs you can add me as second reviewers to make this pass?
