5767f1f912 OperatorNode: Fix bug from wrong use of getIdentifier 
1+(1+1) with parenthesis set to 'auto' triggered a bug because
getPrecedence gets the precedence of the content of a node, but
getIdentifier still returns the 'ParenthesisNode' identifier in case of
a ParenthesisNode.

8db07e23ad OperatorNode.toTex: BUGFIX: make clear where the exponent belongs to 
Without proper parentheses it's impossible to decide whether an exponent
belongs to the numerator of a fraction or to the entire fraction.

For ConditionalNode, the exponent is hard to see without parentheses.
