Enum renaming misses symbols in function bodies

[phrohdoh]

My original code is as follows:

#[derive(Debug)]
enum MonoError {
    DataContainsNulByte,
    FailedToCreateDomain,
    FailedToOpenAssembly,

    Foobar,
}

// Just for demonstration purposes.
impl Default for MonoError {
    fn default() -> Self {
        MonoError::Foobar
    }
}

// The `self` here is also for demonstration purposes.
impl From<NulError> for self::MonoError {
    fn from(_: NulError) -> Self {
        MonoError::DataContainsNulByte
    }
}

In renaming MonoError to RtError I get:

#[derive(Debug)]
enum RtError {
    DataContainsNulByte,
    FailedToCreateDomain,
    FailedToOpenAssembly,

    Foobar,
}

// Just for demonstration purposes.
impl Default for RtError {
    fn default() -> Self {
        MonoError::Foobar
    }
}

// The `self` here is also for demonstration purposes.
impl From<NulError> for self::RtError {
    fn from(_: NulError) -> Self {
        MonoError::DataContainsNulByte
    }
}

You will notice that the MonoError instances inside of the function bodies were not renamed as expected.

This is essentially the same problem as https://github.com/rust-lang-nursery/rls/blob/master/debugging.md#information-for-paths - we don't have info for components of paths.

Ah yes I see, thank you @nrc. Feel free to close this as a known limitation if desired.

Just tested this and now it finally works as expected! (Modulo self pointing to RtError instead of the root file module, which is a bug)
