This PR fixes a bug that occurs during filter operand changes.
As a date filter can contain values that have a different shape, mainly
date ISO string and hard-coded relative dates, changing the operand
without resetting the value to its default was causing a crash.
This PR also extracts the logic that computes the right part of a filter
chip into a util instead of a difficult to understand ternary, thus
solving small bugs in the value displayed also.
