fix(numberFilter): pass through null and undefined values

When these special values are passed through one-time binding will work correctly.

BREAKING CHANGE: previously the number filter would convert null and undefined values into empty string, after this change
these values will be passed through.

Only cases when the number filter is chained with another filter that doesn't expect null/undefined will be affected. This
should be very rare.

This change will not change the visual output of the filter because the interpolation will convert the null/undefined to
an empty string.
