Closed Issue: Formula engine fails on ranges that point to formulas [8384]

If you put a formula in a cell, then reference that cell via a named range in another formula, the latter formula fails in XLWorksheet.Range().

Steps to reproduce:

1. Create a named range for cell A1.
2. Put a formula in cell A1, e.g. a sum of some other cells.
3. Put a formula in cell A2 that references the range name.
4. Attempt to get the value of cell A2 (or call Evaluate on its formula)
