Fish Setting Doesn't Work

Hi, I have fish installed but I get error below even with setting `"php-sublime-shell": "fish"` in settings.

```
cd /path/to/project/root && /path/to/project/root/vendor/phpunit/phpunit/phpunit /path/to/project/root/tests/Unit/ExampleTest.php
fish: Unsupported use of '&&'. In fish, please use 'COMMAND; and COMMAND'.
```
