Remove window scroll in features/project/job_spec

What does this MR do?

Remove window scroll in features/project/job_spec

We have some tests that execute execute_script "window.scrollTo(0,0)" which is not needed since we are just checking the dom, which end up in a some slower tests.

Move the before block for when job starts environment sub contextes to one block since all of the are the same.

Some formatting fixes to be consistent.
