Danger apparently has three different objects which could contain files
you often want to check:

 - git.added_files
 - git.modified_files
 - git.renamed_files

The problem: If a file is renamed, `modified_files` contains the file
path before the rename. In some Danger checks we use `added_files` +
`modified_files`, which might contain the deleted paths of renamed
files, but missing the new paths of renamed files.

So we need to consider `renamed_files` as well.

Enable frozen string for lib/gitlab/*.rb

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.
