ChertPostListTable::get_doclength skips new documents after flush

Description

Chert's get_doclength sometimes skips documents, leading to Xapian throwing DocNotFound when retrieving the document for a search result. I've attached a testcase that passes with Flint and fails with Chert. Resetting doclen_pl on every call makes the problem go away, so a workaround might be to just reset it after a flush.

The cursor isn't going to be valid for the new table revision, so resetting doclen_pl on flush() is the appropriate fix, and makes your testcase pass.

Comitted to trunk in r13445. Chert-only, so nothing to backport.
