EDIT(@isaacs): pattern should be `\.tsx?$`, not `\.ts?$`.  We don't want
to run a `after.t` with typescript, so the `s` is not optional.

EDIT(@isaacs): move lint to postsnap, and do --fix by default.  We
always have to run snapshots before pushing a new version, and expect to
get code changes as a result.  This is much more convenient than having
tests just not run becuase of some scaffolding or something.

Breaking change, tho

Fix: #795

Fix: #733

Also, don't privilege Travis-CI anymore

otherwise CI on old npm versions don't include it, and the tests fail
