Adjustment to meet Vaadin 8.14.1's newer Jsoup dependency

[mpetris]

Description

Jsoup's old TextNode constructor had two arguments and the second one was marked deprecated. The newer version of Jsoup 1.14.2 which ships with Vaadin 8.14.1 has only one argument with the deprecated one having been removed. This fix corrects the call to the construtor by passing just one argument in.
