Fix #105965: Add fur modifier properties missing UI data

Currently assigning values to IDProperties clears their UI data.
That is fixed by #106161, but that is too risky for 3.5. Instead,
work around the issue by triggering `MOD_nodes_update_interface`
function which recreates the UI data of the modifier properties.
