Updated the "update test runs task"

The task is encountering an issue because
it expects a list of objects with a path
attribute, but instead, it is receiving a
string.
The map(attribute='path') filter is being
applied to a string, which causes the error.

To resolve this, ensure that xml_files.files
is a list of dictionaries, each containing a path key.
