The `describe` method doesn't work on `ComplexMap`

[jkyang92]

The following code fails

describe id_(complex QQ^1)

With the following error:

error: no method found for applying unhold to:
                   {    1              1  }
     argument   :  {0:QQ  <--------- QQ :0} (of class VerticalList)
                   {         | 1 |        }

The cause appears to be that expression(ComplexMap) appears to return a VerticalList instead of an Expression.

I'm not sure if this is directly related or not, but occasionally if I have a typo in a method name I get errors like this involving complexes:

stdio:87:42:(3):[3]: error: no method for adjacent objects: not displayed

Why does it not display the inputs, no clue!
