electron: upgrade to 1.8.2, node 8.2.1, chromium 59 (#1275)

* electron: upgrade to 1.8.2, node 8.2.1, chromium 59

* server: update snapshots for node

* server: try to debug timeouts for mochawesome

* bump zunder

- node-sass 3.13.1 does not work with Node 8, since we’re upgrading the
project to node 8.2.1, we needed node-sass 4.5.3+. This node-sass dep
was coming from gulp-sass dep in zunder which has since been updated

* server: figured out that fixture scaffolding can cause timeouts

* bump zunder - get fix so that asserts are not prefixed with /

* server: use our own heroku example app

* use cypress/browsers:chrome64 docker image on Circle with Node 8

* update root folder name

* add hash to root cache

* disable permissions test, because cannot run as root

* server: only disable test in CI

* test new binary against other projects

* all: rename cypress-monorepo -> cypress

* scripts: use latest docker container

* server: don't skip as this messes up hooks which cause failures downstream

* driver: bump timeout for zonejs

* server: make tests pass for node 8.2.1 and 8.4.0
