Fix array handling in SchemaOf type

[chasecaleb]

1. Move array before object so that inference works correctly
2. Include Lazy as part of ArraySchema's generic, to match the class definition

Here's a quick snippet that illustrates why 1 is necessary:

export const array: Array<string> = ["abc"];
// Valid - an Array is a Record (note: AnyObject is a type alias for Record<string, any>)
export const record: Record<string, any> = array;
// Doesn't compile
export const anotherArray: Array<string> = record;

By the way, I noticed that eslint isn't checking the $ExpectType comments in test/type.ts... I investigated it for a little bit, but ran into more problems so I gave up. You need to add --ext=.ts,.js when running eslint to make sure it checks the ts file, but then eslint started to give parser errors and I lost motivation. That's my excuse for not adding tests, sorry about that.
