set -ev prints every command executed and fails the entire script when
any command fails. This prevents false-positive cases where only one of
the tasks fails. For instance when there are LaTeX specific errors which
only cause the bookdown::pdf_book script to fail. In this case Travis still
marks a pull request as if the build passes.
