Description
In the project with nightly toolchain used, Some(22).ex<|> proposes expect_none method which is unstable currently.
But when I autocomplete it, I need to manually add the feature flag to enable the feature.
I would expect RA to add this flag automatically, if not added already.

Research direction
Reproduce the autocomplete case described with the nightly toolchain using Some(22).expect_none, then trace the autocomplete handling for unstable methods and feature-flag insertion. Done means accepting the completion adds the required feature flag when it is absent and does not add a duplicate when it is already present.
