Description

For OAK-3371, I made an improved patch, but that was not used. My patch fixes some problems with the code, for example:

OAK-3371 uses "instanceof" where it is not needed (AstElementFactory for example). The current code is problematic.

One regression that OAK-3371 introduced is that "not not contains" is converted to "not contains" instead of "contains"
