Update php-csfixer rules to address problem in 2.7 & new multiline rule

 * yoda_style in 2.7 is dangerous and may result in logic errors. In
 some cases, it also results in invalid syntax.

 * multiline comments prefixed with // now seem to be misaligned, and
 this cannot be disabled, so have changed the relevant comment.
