2 years old and you may have found an easier way of doing so by now, but you can use UnityExplorer
You must be registered to see the links
to edit the font sizes of the text so that they don't word wrap. The github page explains how to use it more in depth, but basically you use the inspector's UI mouse-inspect to choose the text, open the text element in the inspector (by double clicking on it), and then search for fontsize and edit it to whatever value you want. There's also an auto size option but I didn't bother checking if it works well for every text element.
