Classes with fluent interface should have a static constructor method - #7

Description
-----------

With @Toflar we have discovered by accident that if a URL is double-encoded (for some reason, doesn't matter) the Contao's `RouteProvider` will eventually throw an error trying to query a database.

```
URL original: drachenlochmuseum-v%25c3%25a4ttis.html
URL decoded: drachenlochmuseum-v%c3%a4ttis.html
URL decoded 2nd time: drachenlochmuseum-vättis.html
```

The decoded URL is used in the database query and that fails because the database driver would like to replace wildcards `%c` with parameters that were not provided.

Stack trace:

```
Exception: Too few arguments to build the query string

If a `tl_article` record still contains `keywords` from previous Contao versions and you reference this article in an `article` content element, the following warning will appear in the back end:

```

```

This is because `$GLOBALS['TL_KEYWORDS']` is only initialised in the front end within `PageRegular::prepare()`. This PR simply ignores it if not set.
