Install both npm and bower dependencies at once.

have same issue bower got wiped out.

gladly bower install fixes it all

[Vishal-Isharani]

also same issue here bower_components and also bower.json got wiped out
have to install bower_components manually using bower

[bbak]

Similar here on Win10 (14393), Node 6.6.0 (x64), yarn 0.16.0: package.json is processed, bower.json is untouched, but bower_components is empty (pruned) after yarn install

If you add the following to package.json, bower install will be called and it works. It is a workaround though:

`"scripts": {
    "postinstall": "bower install"
}`

at a minimum, not wiping the bower_components directory would do. (re-running bower install, without a lock file, has the same issues as yarn tries to fix vs npm).

We've removed support for Bower, see #1441.
