Set NoMultilineReturnFixer priority to run before ArrayIndentationFixer (#7)

Without this, collapsing a multiline return leaves stale indentation
because `array_indentation` has already run (priority 29). Setting
priority 30 ensures the return is joined first so indentation is
recalculated correctly.
