tests: fix test-sparse-revlog

This one is not covered by the CIbecause I requires an expensive artifact to be
cached. So it goes out of think on regular basis (we should fix that…)

The test ouput was affected by e706bb41fdb3 as we filtering now happens sooner,
removing for the output.

 ====================================
 Test delta choice with sparse revlog
 ====================================
 
 Sparse-revlog usually shows the most gain on Manifest. However, it is simpler
 to general an appropriate file, so we test with a single file instead. The
 goal is to observe intermediate snapshot being created.
 
 We need a large enough file. Part of the content needs to be replaced
 repeatedly while some of it changes rarely.
