ParenthesesUtils#removeParensFromPolyadicExpression: check operand validity

As processing the previous operands may completely rewrite the whole polyadic expression, we have to stop if this happens
No need to find the replacement and process the tail: it's already processed in removeParensFromParenthesizedExpression
Fixes EA-141996 - PIEAE: CompositePsiElement.getContainingFile
