Remove second argument from textToQualifiedNameList

Hi,

i found out that the function textToQualifiedNameList doesn't use the
second argument it receive (caller). i suppose in the past was used
and now it is useless, if that is the case here is a patch removing.
Or are any reasons to keep that argument?
