Add use of reporter lang method

[msaglietto]

Summary
Continuing with #1387 now most of the files are cover ..
Some missing are:

https://github.com/yarnpkg/yarn/blob/master/src/lockfile/parse.js#L178 that dont have access to a reporter

https://github.com/yarnpkg/yarn/blob/master/src/cli/index.js it would be nice to translate the commander options .. but the definition of the options needs to be moved to after the reporter creation

And if there is any other translation missing let me know

Test plan

Just ran yarn run test and hope for the best

[msaglietto]

It seams the test, not only take to long to run, are not reliable ...

After a few runs locally it fails on should expose npm_config_argv environment variable to lifecycle scripts for back compatibility with npm (#684) if I run yarn run test

But if I run npm run test locally it fails on install should respect --no-bin-links flag also

And now the build fail in install with arg that has install scripts ... that it seems not related to my changes

Thanks for the PR, let's merge it, could you rebase it please?

@bestander Updated ... 5 test are failing locally and 1 appveyor fail .. but the others pass .. so not sure what to trust

[bestander]

Some tests can depend on network so they might fail, if other CI are fine then it should be safe

#2439 caused by this PR.
Probably an older bug where # is not in ...vars caused escaping of the whole string
