[IMPROVEMENT] Honor layout when no Store_Last_Message is set to false

    When no file filters are specified in the server whitelist, the Android system is incorrectly given a mime type filter list including a single empty ("") mime type. Naturally, nothing matches this, and no documents can be selected for upload.
