use Cypress v3 (#42)

* chore: use Cypress v3, npm ci, package lock

* commit package lock file

* run only npm ci

* add comment about machine version

* update .travis file to cache the binary

* update AppVeyor file to cache binary

* just use Node 10 on windows

* install npm v6 on windows

* disable recording on AppVeyor

* skip all tests

* use cypress 3.0.2
