history_sinc.vala: Do not ask 'before' ID on timestamp rangeHEADmaster

According to their devs, for some reason some servers like Prosody
dislike receiving an archive query with *both* a timestamp range and a
'before' ID, returning an item-not-found error in such case. An example
query is shown below.

Instead, now the 'before' ID is left empty, which seems to have restored
the expected behaviour.

<iq id='redacted' type='set' to='redacted'>
  <query xmlns='urn:xmpp:mam:2' queryid='redacted'>
    <x xmlns='jabber:x:data' type='submit'>
      <field type='hidden' var='FORM_TYPE'>
        <value>
          urn:xmpp:mam:2
        </value>
      </field>
      <field var='start'>
        <value>
          2026-04-11T02:25:00Z
        </value>
      </field>
      <field var='end'>
        <value>
          2026-04-11T19:41:12Z
        </value>
      </field>
    </x>
    <set xmlns='http://jabber.org/protocol/rsm'>
      <max>
        20
      </max>
      <before>
        redacted
      </before>
    </set>
  </query>
</iq>
