Fix WebDriverWrapper.isTextPresent usages

[labkey-tchad]

Rationale

WebDriverWrapper.isTextPresent no longer html encodes the text that is being searched for.

java.lang.AssertionError: Expected response 'This is a response to This is a real message 1754798280718 by user <a href="mailto:moderatorreviewapprovedauthor@messages.test" rel="nofollow">moderatorreviewapprovedauthor@messages.test</a>' was not present on the thread page.

Introducing a separate isHtmlPresent method for cases that do want to search for HTML.
