title: Database.Delete() throws InvalidOperationException
body: <p>When I use a relative path (AttachDbFilename=|DataDirectory|\Database1.mdf;) in my connection string  Database.Delete() gives me </p>
  
  <p><em>InvalidOperationException : Unable to delete the database. There is no database that corresponds to the given AttachDBFileName.</em></p>
  
  <p>When using an absolute path deleting works. I know that my relative path is correct because other database operations work with it too.</p>
  
  <p>I thought not being able to use a relative path with super directories (\..\) was the only limitation?</p>
  
  <p>I'm using Entity Framework 6.1.1 and LocalDB.</p>
