Error using ODT and HTML styling to generate PDF

[rodneicouto]

xdocreport version is 2.1.0

When attempting to generate a PDF using ODT, Freemarker and HTML with the example below, I encounter an error because the intermediate ODT file generated has a <text:p> tag that is not properly closed.

<h2>Lorem ipsum dolor sit <em>amet, consectetur adipiscing</em> elit </h2><p>laborum.
</p><p></p><p></p><h2>Cláusula de (<em>livre preenchimento</em>)</h2>

The attached project reproduces this behavior.

The incorrect tag can be seen highlighted in the attached image.

bug_report.zip

the stack error is:

In the tests I conducted, the error occurs when there is more than one header and <em> or <i> tags are used within them
