ATR-25505: fixing issue with removing two variables from the same container
As it says in the title, this merge requests fixes the issue when two or more variables are removed from the same container. Previously this was overwritten, discovered by @cantel (thank you!!) and reported in ATR-25505. In addition there was an issue if the variable name was a part string of a different variable (e.g. ActiveArea and ActiveArea4vec_eta). This is fixed removing the var+"." instead "."+var from the string.
Tagging also @okuprash for info.
