<p>Added a test for the case of join attrs specified with empty ({} or<br>
undef) vals (i.e. join =&gt; { rel =&gt; { rel2 =&gt; {} } }). These tests pass,<br>
however, the empty {} vals currently produce uninitialized warnings.</p>

<p>For further reference, these warnings were bypassed for RapidApp in this<br>
commit:</p>

<p>This test was added per the request of <a href="https://github.com/ribasushi" class="user-mention">@ribasushi</a></p>
