MongoDB\generate_index_name method doesn't exist.

[Daniel Sørensen]

There's an issue with the createIndex method inside `lib/mongo/MongoCollection.php', where in the event that the '$options' array has no property called 'name' it'll call an undefined method 'generate_index_name' from the 'MongoDB' package.

Additionally there's a similar error where the 'deleteIndex' method calls the same 'generate_index_name' if the '$keys' argument is an array.

The error I am facing:

Thanks for the report. A fix will be released shortly; in the meantime please stick with mongodb/mongodb 1.15 or lower.
