Fix multi-select filter crash when 'in' operator is used

The isMatchingMultiSelectFilter function did not handle the 'in' filter
operator, causing a runtime error when a multi-select field received an
'in' filter (e.g. after converting a SELECT field to MULTI_SELECT while
a view filter was active). Added 'in' support to both the
MultiSelectFilter type and the matching function.
