Fix kdepim-addons autotest EnterpriseHeaderStylePluginTest
Summary:
EnterpriseHeaderStyle::format() returns a chunk of HTML ending with an
unclosed DIV. This patch adds a "</div>" tag in the tests, so that
testHeaderFile() can construct valid XHTML to pass to xmllint, and adds
the DIV to the expected output.
