This is unrelated I just noticed that the MongoPackageForSeries function didn't
have a test, it is trivial, so I added it.

+        var pkg string
+
+        pkg = MongoPackageForSeries("precise")
+        c.Assert(pkg, gc.Equals, "mongodb-server")
+
+        pkg = MongoPackageForSeries("trusty")
+        c.Assert(pkg, gc.Equals, "juju-mongodb")
+}

 func makeService(name string, c *gc.C) *upstart.Conf {
         conf := &upstart.Conf{
                 Desc:    "foo",
                 Service: *upstart.NewService(name),
                 Cmd:     "echo hi",
         }
         err := conf.Install()
         c.Assert(err, gc.IsNil)
         return conf
 }
