Xporter is not working properly with Xray v4.2.5 or higher

Xporter is not working properly with Xray v4.2.5 or higher when we try to include attachments on the report generated.

Steps to reproduce the error:

1. Add images/attachments to Test run Execution evidence
2. Add images/attachments to test step evidence
3. Enable the option "Include attachments"
4. Install the template "Test Execution with Cover Page"
5. Export one Test Execution using the template installed

Xporter (version 6.6.2) will not be able to include attachments.

This error is related to the Xray security fix: 
https://jira.xpand-it.com/browse/XRAY-6499
 

Expected behavior:

Xporter should load the full path where the file is located.
