Link add/edit: Fix config-sheet not properly re-rendered on profile type change (#3141)

Previously, autocomplete for parameter text sometimes did not properly
initialize due to receiving the old config descriptions of the previous
profile type.
This fixes this by making sure the config sheet is re-rendered when the
new profile type config has been loaded.
