Merge #6501

6501: Remove text_edit_builder api from AssistBuilder r=matklad a=Veykril

Also fixes a small bug in `expand_glob_import` in regards to the very nice looking `something::{*}` import when only one item was used. Before it would duplicate the path and just append it, causing the following wrong import `something::something::UsedItem`.
