Community Edition: DROP DATABASE

I have a community edition instance where a second database was created somehow and I want to drop it. When I try the DROP command it gives an error (Unsupported administration command: DROP DATABASE neo4j DESTROY DATA). My instance is hosted by a 3rd party so I don't have access to the file system to delete the database that way. In CE how do you drop a database?

If it may or may not exists (to avoid an error if it does not exist):

DROP DATABASE databaseName IF EXISTS

or

If you know it it exists:

DROP DATABASE databaseName
