Fixes syntax error in Yii1 connector

8ffb171800735049b136934d11f15e8e2ff9b513 introduced a syntax error in the Yii1 connector that prevents tests from running. https://github.com/Codeception/Codeception/blob/8ffb171800735049b136934d11f15e8e2ff9b513/src/Codeception/Lib/Connector/Yii1.php#L10

```
$ php -l vendor/codeception/codeception/src/Codeception
/Lib/Connector/Yii1.php
PHP Parse error:  syntax error, unexpected 'public' (T_PUBLIC), expecting ',' or ';' or '{' in vendor/codeception/codeception/src/Codeception/Lib/Connector/Yii1.php on line 15

Parse error: syntax error, unexpected 'public' (T_PUBLIC), expecting ',' or ';' or '{' in vendor/codeception/codeception/src/Codeception/Lib/Connector/Yii1.php on line 15
```
Looks like a missing ```;```. Adding the ```;``` on line 10 fixes the issue.
