Test definition with special chars created from UI does not match if created by API

Test definition with special chars created from UI does not match if created by API.

How to reproduce:

1. Create a Generic Test manually, and in the Test Definition write a text with special chars (like Square Brackets []) using the Jira/Xray UI.
2. Import a Test Execution result that should match the Test Definition created previously, using the REST API.
3. The import should have matched the Test case created in the first step, but instead, it creates a new one.
4. In the UI, both Test Definitions look the same, but in the database, the manually created Test has a backslash before the left square bracket. This makes the Test Definition values of the to tests different.
