Auto merge of #4301 - flip1995:dummy, r=Manishearth

Bump version of clippy_dummy

The crates.io page of clippy still suggest to install `clippy-preview`
instead of `clippy` I think it's time to change this.

Thanks to the Stuttgart Meetup for discovering this!

r? @Manishearth could you also publish this after merging?

 Installing clippy via crates.io is deprecated. Please use the following:
 
 ```terminal
-rustup component add clippy-preview
+rustup component add clippy
 ```
 
 on a Rust version 1.29 or later. You may need to run `rustup self update` if it complains about a missing clippy binary.
