MPS-16999 Pasting nodes is inconsistent
 - pasting node instead of text only if selected label is "theOnlyCompletelySelectedInBigCell" or the cursor is on first/last position. Pasting if selection is different to allow pasting into the text labels
 - paste was working incorrectly if you copy "1 + 2" ant try pasting it into: myMethod(|);
correcting unit-tests again
