Fix broken build

[afontcu]

Build was broken due to linting error:

[lint] 
[lint] /home/travis/build/testing-library/cypress-testing-library/cypress/integration/commands.spec.js
[lint]   43:5  error  Promise should be returned to test its fulfillment or rejection  jest/valid-expect-in-promise
[lint] 
[lint] ✖ 1 problem (1 error, 0 warnings)

Well, now it's something else

[test] We expected the binary to be installed here: /home/travis/.cache/Cypress/3.4.1/Cypress/Cypress
[test]
[test] Reasons it may be missing:
[test]
[test] - You're caching 'node_modules' but are not caching this path: /home/travis/.cache/Cypress
[test] - You ran 'npm install' at an earlier build step but did not persist: /home/travis/.cache/Cypress
[test]
[test] Properly caching the binary will fix this error and avoid downloading and unzipping Cypress.
[test]
[test] Alternatively, you can run 'cypress install' to download the binary again.

Seems to have been going on for a little while in the build history, related to cypress-io/cypress#2344

Okay, seems fixed. Copied build config from official docs.
