### Steps to reproduce

1. Add a work package to a meeting series template, or to an occurrence, and then move it to the backlog

2. Go to the work package meetings tab


### What is the buggy behavior?

* The counter is (1), but the meetings tab is empty

* This is because the WP in the Begin of the insertiontemplateEnd of the insertion Begin of the deletion backlog/templateEnd of the deletion is being counted, but not displayed


### What is the expected behavior?

1. The counter should not include templated meetings
