Subject: Fix completion of Default struct update syntax

Previously the inserted text was always `..Default::default()` which ends up as `...Default::default()`
if `.` was typed. Now  checks if the current token is `.` and inserts `.Default::default()`
if it is, so `..Default::default()` is correctly completed.

Fixes #6969
