Refactor and fix of the run/apply/let/also intention converter

1) Optimize and refactored code
2) Added support for correct renaming of target identifier to this/it
3) Added support of cases with difficult application targets (like: var x = 1 + 2)
4) Show error hint when refactoring failed for some reason
5) Improved intention applicability checking to eliminate false-positive cases
6) Fixed EA-209577
