trim node version from .nvmrc

[Yvem]

Most editors either add a trailing new line and/or hide an existing trailing newline.

This cause the following error :

Running ". ~/.nvm/nvm.sh && nvm use 4.2.2
 && nvm alias default 4.2.2
" on host "localhost".
@localhost Now using node v4.2.2 (npm v2.14.7)
@localhost-err bash: -c: line 1: syntax error near unexpected token `&&'
@localhost-err bash: -c: line 1: ` && nvm alias default 4.2.2'
Error: Command failed: /bin/sh -c ssh xyz@localhost ". ~/.nvm/nvm.sh && nvm use 4.2.2
 && nvm alias default 4.2.2
"
bash: -c: line 1: syntax error near unexpected token `&&'
bash: -c: line 1: ` && nvm alias default 4.2.2'

this fix it.
