Travis covr check timeout

[MarkEdmondson1234]

The tests are all successful, but the final step of uploading the results to codecov.io fails.

• Last successful build: https://travis-ci.org/cloudyr/googleComputeEngineR/builds/176420079
• First unsuccessful build: https://travis-ci.org/cloudyr/googleComputeEngineR/builds/176660349

I can't see what was introduced in to stop the timeout occuring, maybe its just going over the 20min. The tests themselves avoid timeout via the below in .travis.yaml:

script: 
  - |
    R CMD build .
    travis_wait 40 R CMD check googleComputeEngineR*tar.gz
after_failure:
- find *Rcheck -name '*.fail' -print -exec cat '{}' \;

This one passes Travis but dosen't upload to Covr

https://travis-ci.org/cloudyr/googleComputeEngineR/builds/177248015

after_success:
- travis_wait 40 Rscript -e 'library("covr");codecov(line_exclusions = list("R/options.R", "R/utilities.R"))'
