Dep: status: incorrect projectConstraint sorting order

[darkowlzz]

projectConstraint sort byProject was added in commit https://github.com/golang/dep/commit/73ca5d96c8914e76dc847cdb5c17c2f7f35a0d8e and sorts in reverse order. It should sort in ascending order.

Fixing this would also require reordering the test data in the same commit, for the tests to pass.

Incorrect order (right now):

github.com/foo/deptest-project-3
github.com/foo/deptest-project-2
github.com/foo/deptest-project-1

Correct order:

github.com/foo/deptest-project-1
github.com/foo/deptest-project-2
github.com/foo/deptest-project-3

I can work on this one.
