Drop files broken on Morphic host

[tinchodias]

See BlMorphicEventHandler>>#dropFiles:

dropFiles: anEvent
    "Handle a number of dropped files from the OS.
    TODO:
        - use a more general mechanism for figuring out what to do with the file (perhaps even offering a choice from a menu)
        - remember the resource location or (when in browser) even the actual file handle"
    | numFiles |    
    numFiles := anEvent contents.

    1 to: numFiles do: [:i | | aFileReference handler |
        aFileReference := FileReference requestDropReference: i.
        handler := ExternalDropHandler lookupExternalDropHandler: aFileReference.
        handler ifNotNil: [ aFileReference binaryWriteStreamDo: [ :stream | handler handle: stream in: self dropEvent: anEvent ] ]].

This is broken: FileReference requestDropReference: i.
