Fix update formula call after import.

Description

When importing the first time, the comment is different and therefore the setComment command will be executed, which notifies the project about the changes and updates all formulas. In a second import the comment does not change and so the project gets not updated. The solve dependencies in the spreadsheed did not work because the recursive flag was missing and so the columns get never an update. When adding the flag, the formula gets updated multiple times. One time with the setComment call and one time with the spreadsheet logic. This is not required and so we rename the signals of the set comment command to another signal name because actually we don't care if the comment changes or not. We don't wanna react on it
