Remove usage of pub(crate) from two methods; fixes #787
Remove usage of pub(crate) from two methods; fixes #787

Using `cargo install` builds the code using the installer's local version of rust. For users who aren't yet on 1.18 or above, the presence of restricted visibility functions broke installation. Racer doesn't *need* to use restricted visibility on these, as all crate exports are done explicitly in lib.rs, so this fix should be harmless.
