When the cucumber test prefix is empty, system is not reading the issue key and does not update the issue test and creates a label with the key of the issue

Short Description: When the cucumber test prefix is empty, system is not reading the issue key and does not update the issue test and creates a label with the key of the issue.

Steps to Reproduce:
1 - Navigate to the Global Settings of Xray.
2 - Pick the Cucumber option.
3 - Remove the prefix export from the Test option and save the settings.
4 - Now, import a feature file with the test issue key in it (like: @IssueKey).

Actual Results: System ignores the issue key and creates a new test and puts the issue key as a label in it.
Expected Results: System should update the issue key and not create a label with that key.

5 - The previous behavior is displayed for Preconditions. It also seems that, regarding the Precondition, even with the prefix, the precondition is not updated and a new one is created.
