Unnecessary parentheses added by convertMathExpressionToTeXNode

[taojoe]

Bug description

when I need to set '{a}+{b}' to MathFieldEditingController, the convertMathExpressionToTeXNode add '()' to the expression, which it shouldn't.

To Reproduce

Steps to reproduce the behavior:

1. run the following code with debug , then you will see the node has 5 leaves, the start and the end leaf are '(', ')'

final node=convertMathExpressionToTeXNode(Parser().parse('{a}+{b}'));

Expected behavior

simple expression should not wrap with '()', '()' is only required when a lower priority expression as part of higher priority expression, like plus/minus expression as part of times expression
