Fix #141448: Geometry Nodes: UI panel property name trimming logic Fix

Previously in 95259228d9, property names
within geometry nodes panels are trimmed to make it less verbose if the
property name contains the parent panel's name as prefix, this didn't
take into account where property name can be the same as panel name, in
which case there will be an empty property name which is undesired. So
we should not trim the name in this case.
