tdf#129360: don't try to use uninitialized objects

And also don't forget to re-initialize member list of watch item.

Another old bug masked by hacks removed in commit
62f3f3d92aa204eaaa063b30d7ade44df501b997. E.g., previously in code

Type t1
  var1
  var2
End Type

Type t2
  var1
  var2
  var3
End Type

Sub test
  Dim v1 As t1, v2 As t2, v
  v = v1
  v = v2
End Sub

breaking on line 'v = v1', expanding v in Watch, and stepping to next
line, didn't update the children count. After the change, this surfaced,
and now fixed.
