Fix for 'str object' has no attribute 'name'

[filviu]

I started seeing the following error:

TASK [rossmcdonald.telegraf : Set templatized Telegraf configuration] *************************************************************************************************************************************************
task path: /home/user/.ansible/roles/rossmcdonald.telegraf/tasks/configure.yml:14
The full traceback is:

jinja2.exceptions.UndefinedError: 'str object' has no attribute 'name'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/user/.local/lib/python3.10/site-packages/ansible/plugins/action/template.py", line 138, in run

fatal: [dev17.smartkyc.com]: FAILED! => changed=false 
  msg: 'AnsibleUndefinedVariable: ''str object'' has no attribute ''name'''

I am not sure at which point this started happening - I only discovered when I wanted to add a new telegraf plugin to my infrastructure. By the looks of it the result of the old style concatenation results in a string now instead of a list. This fixes the issue for me but I didn't test more than this.
