Tag "st_CachedMenu" sets incorrect "template" parameter to menu elements

Below is the code, that could be to display website menu top level:

<inp2:m_DefineElement name="menu_element">
<a href="<inp2:m_Link template='$template' m_cat_id='$cat_id' use_section='$use_section'/>">
<inp2:m_Param name="title"/>
</a>
</inp2:m_DefineElement>

<inp2:st_CachedMenu render_as="menu_element" category_id="1"/>

This code works before and after In-Portal 5.1.0 version. Problem arises, when developer tries to use "[b]template[/b]" parameter directly without passing it to m_Link tag.

For example here the result of [b]<inp2:m_Param name="template"/>[/b] tag before & after In-Portal 5.1.0 release:
before 5.1.0 release: "[b]path/to/template[/b]"
after 5.1.0 release: "[b]id:434[/b]" (434 is ID of a section, that is displayed in menu)

Attached patch restored pre 5.1.0 behavior related to "template" parameter value.
