Generator#composeWith should support returning all composed generators when returnNewGenerator were true

generator/lib/index.js

Lines 1102 to 1105 in 5cf1a18

	if (Array.isArray(generator)) {
	const generators = generator.map(gen => this.composeWith(gen, options));
	return returnCompose(generators);
	}

Shouldn't line 1103 be written like this?

-   const generators = generator.map(gen => this.composeWith(gen, options));
+   const generators = generator.map(gen => this.composeWith(gen, options, returnNewGenerator));

Currently, when generator was an array and returnNewGenerator was true, Generator#composeWith only returns an array of this (i.e. the current generator).

I think this is a mistake, although this should be easy to fix.

Fixed in #1252 thanks for reporting.
