Panic with empty array during Get(...) call

[sneko]

Hi,

When using funk.Get(make([]*Xxxxx, 0), "Aaaa.Bbbbb") I get this panic:

panic: reflect: call of reflect.Value.Type on zero Value
goroutine 1 [running]:
reflect.Value.Type(0x0, 0x0, 0x0, 0x0, 0x9f34c0)
	/usr/local/go/src/reflect/value.go:1743 +0x16c

It's related to:
https://github.com/thoas/go-funk/blob/master/retrieve.go#L45-L48

I don't understand exactly why this is happening. I can for sure make a statement my array is not empty before using funk.Get, but maybe funk should return me an empty array?

Thanks,
