rust-analyzer-preview from rustup nightly is out of date

[bstaletic]

Today I tried to upgrade to nightly-2020-08-18 and, while it "worked", rustup installed rust-analyzer with c9c518e as the latest one, which corresponds to tag 2020-07-20. From there I have encountered two problems, compared to nightly-2020-07-08.

1. Allow null or empty values for configuration #5467 is missing
2. YCM is installing all rustup components with third_party/rust-analyzer/ as the root. On the latest nightly, rust-analyzer doesn't find rust-src even though it is installed in the same root. This, however, works on today's HEAD (d21d5e4).

To be fair, I am not sure how rustup nightlies are updated, so I might be complaining to the wrong people.

rust-lang/rust#75631 updated rust-analyzer. It will be available with the next nightly.

Yup, the version in rust-up are not fully up-to-date yet, the recommended way to get ra is still from GitHub release. Hopefully, things will be better since today, as (:crossed_fingers:) we fixed the last couple of build-related bugs.
