Change \undertilde to \utilde (#948)

Browse Source 
* Change \undeertilde to \utilde

In PR #670, I made an error. The function that should have been `\utilde` I named instead `\undertilde`.

There is an `\undertilde` from the `wsuipa` package, but it is a text-mode non-stretchy function. The proper command name is `\utilde`, a math-mode, stretchy function from packge `undertilde`.

This PR fixes my error.
