Get rid of hokey dependencyMapList stuff.

Get rid of hokey dependencyMapList stuff.

Now that hosted deps in tests can be just like they are in normal
pubspecs since the server URL is in an env var, we can simplify
the tests.

I'm not a huge fan of how this makes the non-hosted dependency specifications
more verbose, with duplicated names. Can't we keep dependencyListToMap and just
get rid of dependencyMap?

It makes them only a little more verbose, but I really like that the maps now
look just like they do in the pubspec. The old DSL-like format for the maps was
always a bit confusing and hard to remember for me.
