[FW][FIX] export: export non-Excel formulas as value

[fw-bot]

Current behavior before commit:
Since the commit 201aea7, when formulaCell is a FormulaCellWithDependencies, content might be set to raw formula even if it is not readable by Excel.

Description of the fix:
Prevent content to be set to the raw formula if isFormula === false.

Example of steps to reproduce the issue:

• Write a number in A1
• Write =FORMAT.LARGE.NUMBER(A1) in A2
• Save as XLSX and open in Excel -> A2 is not evaluated by Excel

• new/updated/removed commands are documented
• exportable in excel
• translations (_t("qmsdf %s", abc))
• unit tested
• clean commented code
• track breaking changes
• doc is rebuild (npm run doc)
