Fix T95756: Crash inserting geometry node after linking modifier
The root issue was caused by a mistake in modifier copy data which was
wrongly re-generating source modifier data identifier.
The c8cca8885181 simply exposed a bug in code which always was there
since the modifiers session UUID was introduced.
Shows an importance of const qualifier :)
