// The point of this test is to ensure that mongorestore successfully
// constructs indexes when the database being restored into has a
// different name than the database dumped from.  There are 2
// issues here: (1) if you dumped from database "A" and restore into
// database "B", B should have exactly the right indexes; (2) if for
// some reason you have another database called "A" at the time of the
// restore, mongorestore shouldn't touch it.
