[FIX] evaluation: handle throwing error on each vectorized position

Before this commit, if an error was throw when evaluating a
vectorized formula, then the evaluation stopped and only the
cell with the formula was marked as an error.
No other values ​​were spread.

This behavior is functionally false, because depending on the
arguments passed, it is possible that on this vector position,
the evaluation does not return an error.

This commit changes that by making sure to try for each vector
position if the evaluation works. Even though it only spreads
errors in certain cases.

closes #4768
