Fix travis write errors. (#1445)

For reasons unknown, after the latest update of the Trusty environment on Travis,
we encountered write errors for the three Clang builds. As suggested here
https://github.com/travis-ci/travis-ci/issues/4704#issuecomment-321777557,
adding filter_secrets: false to the .travis.yml fixes the problem.

Note: switching back to the deprecated builds did not fix the problem.
