Move bower.json test deps into devDependencies field

[JordanMartinez]

Moves test dependencies into the proper field for the bower.json file. This unblocks the issue I discovered here: purescript-node/purescript-node-streams#54 (comment)

Deps were determined by looking at test.dhall.

The change is good, but the previous state was what Spago has generated, so it will happen again next time I try to spago bump-version.

Ah... that's why this happened. Well, it fixes the problem for now. Migrating to Spago in the Node libraries might be the best way forward.

I have two questions about this:

1. What problem did the incorrect bower.json cause that made you notice the discrepancy?
2. Can we drop support for Pulp now? Or is it still necessary for something?

I cut a new version v7.5.3 just now, but I had to do it manually via git tag, because running spago bump-version would have reverted the bower.json change. This is tricky.

I'm updating the Node libraries. In the node-streams library, we decided to integrate node-streams-aff into the library itself, breaking away from tradition that any Aff-related wrapper exist in its own repo. However, that repo uses spec to do its tests. Rather than rewriting the tests, I just used it as-is so we could get a release out. But because node-streams uses bower for its dependency management, it hit the issue linked in the opening thread.

Can we drop support for Pulp now? Or is it still necessary for something?

I'm not sure. Most people are likely on spago, but bower+pulp is what most of core is on.
