Fix continue statement within switch/case keeping original behavior (#278)
Fix continue statement within switch/case keeping original behavior (#278)

continue statements within switch/case statements always have
behaved like break (ending the switch). Only exception is when
they are within a loop and we may want to use 'continue 2;'
instead (to jump to next iteration).

PHP7.3 has added a PHPWarning for all this switch/case/continue
uses (https://wiki.php.net/rfc/continue_on_switch_deprecation) so
this just changes is to the BC equivalent break. As far as there
isn't remaining code in the loop after the switch, it is 100%
the same than a continue 2.
