scripts/travis-setup.sh fails with 404 for nightly release tarball

[blueyed]

The script to install the nightly build on CI currently fails.

The script is:
eval "$(curl -Ss https://raw.githubusercontent.com/neovim/bot-ci/master/scripts/travis-setup.sh) nightly-x64"

https://raw.githubusercontent.com/neovim/bot-ci/master/scripts/travis-setup.sh tries to download neovim-linux64.tar.gz, but the file seems to have been renamed to nvim-linux64.tar.gz (so neovim was changed to nvim).

Correct: https://github.com/neovim/neovim/releases/download/nightly/nvim-linux64.tar.gz
