Fix local integration tests

[nLight]

This PR fixes the testing env for integration tests
and puts some ducks in the row around naming conventions in the npm scripts.

Testing

Testing OSS:
npm config delete externalplugins - to disable plugins
npm run start:testing
npx cypress open

Testing EE:
npm config set externalplugins <path> - to enable plugins
npm run test:integration:plugins:setup - to copy plugins test. Workaround for cypress
npm run start:testing
npx cypress open

Both should be working

Trade-offs

I couldn't hold myself from cleaning up documentation/scripts

I tried to test this but got an error in the cypress UI (EE and OSS):

[GeorgiSTodorov]

Both work for me.
@natmegs , which cypress version are you using?

[pierrebeitz]

who is that DEBUG for?

[nLight]

fair, removed

[pierrebeitz]

what's the benefit over just turning watch off entirely?

[nLight]

We could, I just restored the config we've had. I believe we still would like to recompile the code as we adapt it. Completely disabling it would mean stoping and restarting the npm run start:testing

[pierrebeitz]

I have 2 browser-options to test in. If i use Electron everything works just fine. When using Chrome (which is the default for me) i get the same error as @natmegs.

Is this expected? If so: can we add a hint somewhere?

If not expected: i noticed that chrome switches to a route at port 4200 instead of staying on the cypress-port. Maybe that's indicating something :)

[GeorgiSTodorov]

Run all specs doesn't work for me either. But individual tests work in Chrome. I use Chrome 71 on Ubuntu 18.04.

[mperrotti]

I'm having the same issue Natalie mentioned.

[nLight]

@mperrotti @natmegs does this trick fixes that for you cypress-io/cypress#1872 (comment) ?

[mperrotti]

@nLight - that worked for me :)
