[ACS-5480] Bug Fix for multiple process/task filters (#8757)

* added a check before pushing filters

* moved the check inside a method and added unit tests for method

* renamed duplicate variables

* improved unit tests

* linting fixes

* linting fixes

* linting fixes

* removed unnecessary expects

* linting fix and added JS doc

* linting fixes - removed types from doc

* added unit tests for createDefaultFilter scenario

* linting fixes

* moved mock test data to mock data files
