Previously, bower2bazel tried to fetch whatever was registered in
bower with the package name. If the package author was specified it was
ignored. There was an issue with installing a new package (paper-button)
in which bower tried to fetch the wrong dependency. (paper-ripple).
This change updates the package to use the original source, so that the
bower-archives file looks like:
bower_archive(
name = "paper-ripple",
package = "polymerelements/paper-ripple",
version = "1.0.10",
sha1 = "21199db50d02b842da54bd6f4f1d1b10b474e893")
