Subject: [PATCH] Freemius: Check _parent object for using method

A proposed solution for an error reported in this [Slack thread](https://podswp.slack.com/archives/C02SVLHQF/p1631628235171000).

It appears that `$this->_parent` can contain either an object or a boolean.
This should resolve the error by checking that it's an object before attempting to use the method `->is_anonymous()`.

It looks like `$this->_parent` is used in other places in this class.
Unknown if the `boolean` vs. `object` detail effects any other functionality.

Error:
