Duplicate date/time data for XMM-Newton

[ronaldbradford]

Looking at what satellites are doing now, I get two entries for XMM-Newton.

I suspect the updated schedule was changed, and we do not delete any existing data as the observation ids are not different. We need a way to delete data (for the range of date/time we are reloading)

db.schedules.find({ start: { $lt: new Date()}, end: { $gt: new Date()}})
