Page title of unnamed queries is hardcoded in different template files.
Rather than redefining it several times, it should only be redefined in one place.
Perhaps in the model file ? At least in app.py only.
For example, one of them is :
```
{% if query.title %}{{query.title}}{% else %}Untitled query #{{ query.id }}{% endif %}
```
