Bug Description:

➜  ~ mysql -P9306 -h0 -e "drop table products"; curl -sX POST http://0:9308/products/_create/ -d '{   "title": "Yellow Bag with Tassel",   "price": 19.85 }'
ERROR 1064 (42000) at line 1: DROP TABLE failed: unknown table 'products'
{"error":{"type":"illegal_argument_exception","reason":"Rejecting mapping update to [products] as the final mapping would have more than 1 type: [_doc, _create]"},"status":400}%
➜  ~ mysql -P9306 -h0 -e "desc products"
