Ignore version checking if building latest tag.

[bmaher]

Part of #6.

Description

This PR fixes a bug where Travis CI builds tags after merges to master, resulting in a failure in the version checking script (versions matched between master and tag).

Instructed Travis to ignore all branches matching a regex representing tags /^v\d+\.\d+(\.\d+)?(-\S*)?$/.

Review

Reviewers' checklist:

• If this PR implements new flows or changes existing ones, are there good tests for these flows? If this PR rather removes flows, are the obsolete tests removed as well?
• Is the documentation still up-to-date and exhaustive? This covers both technical (in source files) and functional (under docs/) documentation.
• Is the changelog updated?
• Does the new version number correspond to the actual changes from this PR? In doubt, refer to https://semver.org.
