Resolve leaves import resolutions in an inconsistent state

[jseyfried]

For example,

mod foo {
    pub mod bar {} // This defines bar in the type namespace
    pub use alpha::bar; // This defines bar in the value namespace

    // This should define baz in both namespaces, but it only defines `baz` in the type namespace.
    pub use self::bar as baz;
    pub fn baz() {} // This should collide with the imported `baz`, but now it does not.
}

pub fn f() {}
mod alpha {
    pub use self::f as bar; // Changing this to `pub fn bar() {}` makes the imports consistent
    pub use super::*;
}

fn main() {
    foo::bar();
    foo::baz(); // This errors
}

This is caused by this code, which incorrectly reports that the import of bar as baz fails in the type namespace.
