Add FormulaRange to IgnoredErrors Possibilities

[oleibman]

When I implemented IgnoredErrors (PR #3508), I dealt only with those that I understood well enough to come up with an example. I finally found an example for FormulaRange in the wild, so this PR adds it. Still unsupported are calculatedColumn, emptyCellReferece, listDataValidation, and unlockedFormula.
