Commit Message

Inga Stotland March 16, 2023, 6:07 p.m. UTC 
This fixes the situation when subsequent requests to get a node
composition result in appending element's model list with duplicate models.
This adds a check for a presence of a model on a element when attempting
to add a new model ID to a model list on this element.
