Hooks are duplicated on got.extend(...)

[szmarczak]

This is because defaults.hooks is set on options.hooks twice:

got/source/core/index.ts

Line 556 in 1f6ac45

options = {...defaults as NormalizedOptions, ...options};

got/source/core/index.ts

Lines 784 to 794 in 1f6ac45

	for (const event of knownHookEvents) {
	const defaultHooks = defaults.hooks[event];
	if (defaultHooks.length !== 0) {
	// See https://github.com/microsoft/TypeScript/issues/31445#issuecomment-576929044
	(options.hooks as any)[event] = [
	...defaults.hooks[event],
	...options.hooks[event]!
	];
	}
	}
