Subject: [PATCH 2/5] tests/: added new test_4790().

tests/test_pagedelete.py:test_4790(): New test, expects the current incorrect
behaviour, checks workarounds fix the issue, that new Document.save() flag
<raise_on_repair> works, and that new Document.repair() works.

tests/resources/test_4790.pdf: new input file.
