Helper for assertUniqueText and assertNoUniqueText.
It is not recommended to call this function directly.
$text: Plain text to look for.
$message: (optional) A message to display with the assertion. Do not translate messages: use format_string() to embed variables in the message text, not t(). If left blank, a default message will be displayed.
$group: The group this message is in, which is displayed in a column in test output. Use 'Debug' to indicate this is debugging output. Do not translate this string. Defaults to 'Other'; most tests do not override this default.
$be_unique: TRUE if this text should be found only once, FALSE if it should be found more than once.
TRUE on pass, FALSE on fail.
