Don't activate getPresentation() method from parser tests

Calling this method from frontend tests caches empty presenters
in KeyedExtensionCollector that makes plugins tests fail.
Debugger: implement getSourcePosition for fields
Debugger tests: move stepping tests
Debugger tests: render line properly
Debugger: wrong stepping through the loop with continue label
 #KT-5776 Fixed
 #KT-5664 Fixed
Debugger tests: do not create breakpoints for FakeLightClassForFileOfPackage because we create them for KotlinLightClassForPackage
Renamed ReferenceSearcherImpl to IdeaReferenceSearcher
Repackaging
Minor
Big refactoring in j2k converter to support java&kotlin code updating to reflect changes in declarations produced by conversion (work in progress but all tests pass)
J2K: checked that field name change is correctly handled for usages in other converted classes as well
J2K: fixed conversion of base class constructor arguments
J2K: fixed conversion of default parameter values and annotation arguments
J2K: refactored code to make createDefaultCodeConverter() private
Removed workaround for compiler bug which has been fixed
J2K: processing usages of get/set methods in the code being converted when converting them into property
J2K: conversion with usage processing across multiple converted files works in tests (but not in real life yet)
J2K: memory optimization
Converted JavaToKotlinAction and JavaToKotlinActionUtil into Kotlin and merged into one class
JavaToKotlinAction refactorings + minor fixes in the logic
