Extension doesn't work if there's more than 1 Nightly Toolchain

[CryZe]

Version of VSCode: 1.31.1
Version of the extension: 0.4.0
OS: Windows 10 64-bit

Description: Neither RLS nor Racer start at all anymore. It seems like the extension gets confused by me having both nightly-msvc and nightly-gnu installed, so it thinks that there's no toolchain installed instead.

Output of the "Rust logging" channel:

DEBUG: activate: getNightlyToolchain: There are 2 nightly toolchains
DEBUG: RlsMode: start: enter
DEBUG: Rustup: isRlsInstalled: getNightlyToolchain: There are 2 nightly toolchains
ERROR: Rustup: isRlsInstalled: no nightly toolchain

Deleting one of the nightly toolchains fixes it.

Update: Okay, so RLS gets stuck in an infinite loop while compiling with rustc. Legacy toolchain works flawlessly.

Yep.
That's what #280 is about.

It already did ask me and it stored it in the settings, but completely ignored this apparently. Whoops, that question was about the "normal toolchain" apparently?!

@CryZe,
Yes it is for the normal toolchain.
A lot of people use the stable toolchain.
I added "rustup.toolchain" to let developers decide which one to use.
I thought people usually have the only one nightly toolchain.
That's not the hard to solve, but I didn't want to stop publishing a new version.
