Curly braces in JSON keys of criteria causes error when test fails

Curly braces in the contents of test criteria are meant for insertion of variables. However, you can use curly braces in keys without having it be substituted for variables. There aren't any issues when using this functionality when tests are passing.
When a test using curly braces in a JSON key fails, however, and error will occur if the test fails, causing pytest and Tavern to fail completely. Below is a log of this error occurring.
