As an user, I got error's on log file when I try to export issue type "Bug" inside Defects

To reproduce this error follow the steps:

• Create a issue type "test"
• Inside the "test" create a new "Test Execution"
• Inside the "Test Run" of "Test Execution"
• Add a defect on test step of issue type "Bug"
• Try to export with the template attached

After this, check the log file. It'll be with the following error message:
[c.x.j.mapping.integration.XrayIssueMappingLoaderV2] An error as occurred while Xporter is geting test step info from Xray: Issue '<Issue Key>' is not of types Test
