Correct error message when inserting docs to non existent scope and collection

a) Try and insert a document to collection that does not exist:
Inserting doc to an non existing collection

Expected Result - LCB_ERR_COLLECTION_NOT_FOUND (211)

B) Try and insert a document to collection, where scope does not exists - in the case both scope and collections don't exist.
Inserting doc to an non existing scope
Expected Result - LCB_ERR_SCOPE_NOT_FOUND (217)

With 3.1.2 - the error is LC_TIMEOUT
