Replace a test expression to prevent a logical short circuit

In file: structured.py, method: interpolate, a logical expression uses the identity operator. A new object is created inside the identity check operation and then used for matching identity. Since this is a distinct, new object, it will not match with anything else. As a result, the identity check will have a logical short circuit and the program may have unintended behavior.

The following binary operation

 profiles is not []

compares a newly created object with identity operator which will always evaluate to True.

I suggested that the logical operation should be reviewed for correctness.

Alpha-Omega is a project partnering with open source software project maintainers to systematically find new, as-yet-undiscovered vulnerabilities in open source code - and get them fixed – to improve global software supply chain security.

The bug is found by running the Intelligent Code Repair (iCR) tool by OpenRefactory and then manually triaging the results.
