`WP_Query` discards most non-array date values ('year', 'monthnum', etc) by
casting to integer. Since <a href="https://core.trac.wordpress.org/changeset/25138">[25138]</a>, the 'm' parameter has been handled
as a string; see <a href="https://core.trac.wordpress.org/ticket/24884">#24884</a>. However, the string-handling introduced in <a href="https://core.trac.wordpress.org/changeset/25138">[25138]</a>
blindly attempted to handle arrays and other non-scalar types as strings,
resulting in PHP notices and invalid MySQL syntax.
Props vortfu.
Fixes <a href="https://core.trac.wordpress.org/ticket/36718">#36718</a>.</pre>
