mongo error: duplicate id on insert attempt

[cch5ng]

error like:

• Exception in callback of async function: MongoError: insertDocument :: caused by :: 11000 E11000 duplicate key error index: meteor.nytfeeds.$id dup key: { : "nythttp://rss.nytimes.com/c/34625/f/640350/s/4c69cf70/sc/7/l/0L0Snytimes0N0Cpolitics0Cfirst0Edraft0C20A150C120C220Canalysis0Eof0Edonald0Etrump0Etax0Ep..." }
• in this case, it was the 15th feed (out of 20)
• the initial feeds insert works ok (when collection is empty) but when collection is populated, this error occurs (only for nytimes, not npr) during function where try to clear old collection and insert current feeds

[cch5ng]

may need to clear all items from collection before trying to insert any of the current feeds

[cch5ng]

• fixed for nytimes and npr feeds
