190 Fix ignore all errors

In #136 we accidentally ignored all errors instead of just the one error:
"Unsafe usage of new static()."

This results in drupal-check failing with the following message:
 -- -------------------------------------------------------------------------- 
     Error                                                                     
 -- -------------------------------------------------------------------------- 
     Ignored error #Unsafe usage of new static()# has an unescaped '()' which  
     leads to ignoring all errors. Use '\(\)' instead.                         
 -- --------------------------------------------------------------------------
