Qi Xiao ab88de7c15 Fix ScanToGo's error message when ptr points to an interface. 
When the destination to scan into is an interface, its zero value is simply a
nil interface, losing the information of the original type and resulting in
error messages like "need nil, got $actual-type".

ScanToGo now handles this case specifically, and uses the string representation
of the interface type in the error message.

Before:

~> ns []
Exception: wrong type of argument 0: wrong type: need nil, got list
~> var x~ = x
Exception: wrong type: need nil, got string

After:

~> ns []
Exception: wrong type of argument 0: wrong type: need !!hashmap.Map, got list
~> var x~ = x
Exception: wrong type: need !!eval.Callable, got string

This is still not ideal, since the "need" type is not given as an Elvish "kind",
but it's much less confusing than than old "need nil" messages.

This fixes #715.
