Default all conditionals to 0

[nguyentvan7]

Describe your changes

• Default all conditionals to 0 inside sr-formula.
  • If we ever have a NumConditional that uses prod ex for some reason, we will need to have a new entry in qt for condWithDefaultOne or something. Otherwise, this default 0 will cause those conditionals to always be 0. That would require there to be a use case where 2 values are writing to the same conditional for some reason, which doesn't really make sense.
• Add a default value to ListConditionals to have def (default 0) when set to 0 (such as above)

Testing/validation

Tested using WIP CalcContext that contains hard-coded conditional data. Default value was working as expected, and a specified conditional would override this default.
