* Checks if casting an expression to __toString() is allowed by the sandbox.

[15] Fix | Delete

[16] Fix | Delete

* For instance, when there is a simple Print statement, like {{ article }},

[17] Fix | Delete

* and if the sandbox is enabled, we need to check that the __toString()

[18] Fix | Delete

* method is allowed if 'article' is an object. The same goes for {{ article|upper }}

[19] Fix | Delete

* or {{ random(article) }}
