Additionally, this changes createIndexes() to no longer allow an empty array as input. The index management spec doesn't state that empty input must be accepted, so I'm not sure why we had that behavior.

Invalid arguments and options constitute a logic error, so InvalidArgumentTypeException may be used. For runtime errors (e.g. server returned something we didn't expect), UnexpectedValueTypeException may be used.

Syntax error typo

Let's also not assume that origin is the appropriate upstream remote (it may be a local fork).
