- FIX bug when split email message by `to_keep` parameter. When the html code is split, it is broken. As a result of this, when it use `fromstring`,
it try to fix this by closing tags.
Example about fixed functionality:
message:
`
<table>
<tr>
<td>
{to_keep}
</td>
</tr>
</table>
`
Split messsage inside `remove_href_odoo` function:
part[0]
`
<table>
<tr>
<td>
`
--------
part[1]
`
</td>
</tr>
</table>
`
-----------------
Result when join by `to_keep`
`
<table>
<tr>
<td>
{to_keep}
</td>
</tr>
</table>
`
