Default to a 4K x 4K browser window in Robot tests

[Rotonen]

I'm in the process of trying to unify Robot test setups and teardowns. This is a part of that effort.

Also re-enabled two previously disabled Robot tests.

In tandem with plone/plone.app.robotframework#110
Closes #2864

@Rotonen thanks for creating this Pull Request and help improve Plone!

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass.

Whenever you feel that the pull request is ready to be tested, either start all jenkins jobs pull requests by yourself, or simply add a comment in this pull request stating:

@jenkins-plone-org please run jobs

With this simple comment all the jobs will be started automatically.

Happy hacking!

Seems okay, but this does not really change anything about 4Kx4K, right? That is handled in your merged p.a.robotframework PR. Or does changing Plone Test Setup to Plone test setup change anything? Does the capitalisation matter?

[Rotonen]

I've done the work with a script.

At least Products/CMFPlone/tests/robot/test_controlpanel_actions.robot has actually changed in regards to how it is now set up.

I can still happily clean up and drop the meaningless capitalization changes, if so desired. I am not in any particular hurry with this process.

[mauritsvanrees]

If it is more consistent after this change, it is good.

[Rotonen]

Part of the stability is also future proofing stability over time. If we have the exact functionally same setups everywhere, local copy pasting will lead also to a new test, which works, and keeps working.

LGTM

@mauritsvanrees I've also slipped through a botched changelog entry through here. Sorry.

Okido, fixed on master in d1fcfd0. No problem.
