Higher than and lower than frontend filters are not working with formulas

In !1950 (merged), I updated viewFilters.js to parse the input value according to fieldType and added support for higher_than and lower_than filters for duration fields.

As noticed in the community (https://community.baserow.io/t/coloring-rows-acording-to-a-calc-formula-field-doesnt-work/4283) this is not working with formula types.
