Since merging #665 `serendipity_plugin_history`
breaks with a SQL error message on every archive
page but the first one; see #693 for reason
and context.
Unset `$serendipity['GET']['page']` before
calling `serendipity_fetchEntries(`)` (and
reset afterwards) to fix that. That's the
correct way, I think, as
`serendipity_fetchEntries()` is not called
in page context here.
