Suggest a prelude glob import if you try to import an item inside of one

[seritools]

I'd love to have the opportunity to import a full <crate>::prelude::* when importing an item that is inside of that prelude.

Example

foo.context(NotEnoughFrobnicationSnafu)?;
    ~~~~~~~ <context is the ResultExt::context trait fn from snafu, but the trait is not imported yet>

On opening the suggestions, currently it shows: "import snafu::ResultExt".
I'd like to have a second option "import snafu::prelude::*".
