Lbudginas/#428 comment search operation type search trigger

#428 (closed)

• Update comment search after operation type changes
• Reset operations to default as null instead of []

NOTE:

On backend default operationTypes is null , we should set operationTypes as null when we want to reset operation type search instead of setting it as empty array []. Setting it as empty array will pass empty operationTypes parameter to request such as : ...?operation-types= which was causing issues. If I missed reset some operation types as null instead of [] , we should be aware of that in a future.
