fix(numberFilter): convert all non-finite/non-numbers/non-numeric strings to the empty string

The previous code for filtering out non-finite numbers was broken, as it would convert `null` to `0`,
as well as arrays.

This change fixes this by converting null/undefined/NaN/Infinity/any object to the empty string.

Closes #6188
