phpcs: Fix Squiz.WhiteSpace.ScopeClosingBrace.ContentBefore violations

ERROR: Closing brace must be on a line by itself
Squiz.WhiteSpace.ScopeClosingBrace.ContentBefore

- For non-empty scopes it means the closing brace must be on a separate
  line. This is already the case in most classes in some cases the "lazy
  closing" is still used.
  array(
   'x' ); // Moved } to next line
  function () { return 'x'; } // Moved } to next line
  case 1:
    stuff; break; // Moved break to next line
- For empty function it serves as a visual distinction between there not
  being a scope block / function body and there being an empty function
  body.
  function foo(); // No body
  function foo() {} // Empty body - violation
  function bar() { // Empty body corrected
  }
