Build creates variables in proxy function's parameter default

#### What are you trying to achieve?
Set a default value in a Helper function that contains `$`

Kinda surprised this hasn't come up - i tried several searches but didn't see anything.
Seems like single-quote strings should be used for generating the proxies, unless there's some special slickness going on to require `" "`.

#### What do you get instead?
The build process wraps default string values in `" "`, which creates a syntax error in the proxy.

```php
/*
* Support/Helper/Foo.php
*/
public function seeSomethingSomething(
mixed $value,
string $message = 'a default $tring parameter'
) { // ^^^^^^ legal, single-quote string
// irrelevant
}
```
```yaml
## Functional.suite.yml

actor: FunctionalTester
modules:
enabled:
- Asserts
- Tests\Support\Helper\Foo
```
```bash
$ php ./vendor/bin/codecept build
```
```php
/*
* Support/_generated/FunctionalTesterActions.php
*/
public function seeSomethingSomething(
mixed $value,
string $message = "a default $tring parameter"
) { // ^^^^^^ illegal expression in parameter default
// irrelevant
}
```
