collect does not play well with enumerate/zip/etc

[my-little-repository]

There is a problem when trying to collect the result of a method returning an enumerator, this was alluded in #13772.

 julia>  collect(take(countfrom(),1))
  1-element Array{Int64,1}:
   1

julia>  collect(enumerate(take(countfrom(),1)))
ERROR: MethodError: `length` has no method matching length(::Base.Take{Base.Count{Int64}})
 in collect at array.jl:253
 in collect at array.jl:272

julia> collect(zip(take(countfrom(),1),take(countfrom(),1)))
ERROR: MethodError: `length` has no method matching length(::Base.Take{Base.Count{Int64}})
 in collect at array.jl:253
 in collect at array.jl:272

The problem probably also exists for methods that expect length to be defined for their arguments.

Dup of #12009

Also works now.
