Description of problem:

When the user provides a SVN repo without the "trunk" folder in it, the analysis will fail with "exit status 1'" error and not further details.

Related to MTA-1717.

In this PR (https://github.com/konveyor/tackle2-addon/pull/46), a change was introduced to display the error details when an analysis failed but its not working now.

Version-Release number of selected component (if applicable): 7.0.1

How reproducible: Always 

Actual result:{}
'[CMD] /usr/bin/svn failed: exit status 1'
Expected result:

The analysis details should display the last lines of the stderr for the user to be able to troubleshoot the issue easily.
