Single quotes are worngly handled if present in SESSION_CONFIG dicts

If a single quote is found in a SESSION_CONFIG dict the value of that specific key will only be parsed until said quote. For example, in this case:

```xml
SESSION_CONFIGS = [
  dict(
    name="test",
    ...
    key="I'm a value"
]
```

the key value will be `I` when it should be `I'm a value`

Escaping the quote like `I\'m a value` doesn't work
