[meta] Fix Drupal.Array.Array.LongLineDeclaration coding standard

Problem/Motivation

The Drupal.Array.Array.LongLineDeclaration coding standard should be applied to Drupal core.

Proposed resolution

@xjm suggests in #15:

This cleanup is large enough that I think we should split it into a few logical chunks (by concept, not by module). I'd suggest:

One patch for fixing the $modules test property.
One patch for fixing calls to drupalCreateUser().
One patch for fixing calls to drupalCreateNode().
Evaluating whatever's left after that and seeing if it should be split up further.
