fix(filters): don't use indexOf with NOT_IN_CONTAINS

[ghiscoding]

• using indexOf returns true whenever the substring is found within a string and that could cause issue, for example "Task1" will be found in "Task123" but that shouldn't be accepted
• also enforce the fact that IN_CONTAINS and NOT_IN_CONTAINS only works with CSV string "Task 1,Task2"
