When doing a dropDatabase() using MMAPv1 on versions from 2.4 -> 3.0.1, the relevant folders which contain the data when using directoryPerDB: true are also removed.
However, when performing the same dropDatabase using the wiredTiger engine and directoryPerDB: true, the directories are left in-tact, and only the related files are removed.
(note, only tested with directoryForIndexes: true in 3.0.1)
