Fix arrays comparison

[michallaskowski]

comparator was trying to use methods of BaseTestSuite which resulted in

609:      if (value1Type = "roList" or value1Type = "roArray") and (value2Type = "roList" or value2Type = "roArray")
610:*         return m.eqArrays(value1, value2)
611:      else if value1Type = "roAssociativeArray" and value2Type = "roAssociativeArray"
612:          return m.eqAssocArrays(value1, value2)

Member function not found in BrightScript Component or interface. (runtime error &hf4) in pkg:/source/testFramework/UnitTestFramework.brs(610)

The same for associative arrays.

Here I changed baseComparator to compare method, which solves this issue. Of course it can also be done differently, but I think this is the easiest fix, and not creating any new objects will help with readability.

@michallaskowski Thank you for your contribution, but we want to keep the ability to provide a custom comparator function. The PR would be closed, but please check the latest version where this issue is fixed with a little bit changed implementation that you've proposed.

Once again thanks for helping us improve the framework. If it's okay, we will add your name in the changelog. We would really appreciate further PR from you! Latest version is here: https://github.com/rokudev/unit-testing-framework/releases/tag/v.1.2.2
