data-sparql and insert-or-replace tests run very slowly on some CI runners
The data-sparql test seems to time out in CI sometimes. This despite having a 180 second timeout.
The same thing occurs with insert-or-replace test.
For example here it timed out after 180 seconds in lists/list-in-select test: https://gitlab.gnome.org/GNOME/tracker/-/jobs/441069 (runner: gcc175-gnome.osuosl.org)
In other cases it can finish in around 30 seconds, like here: https://gitlab.gnome.org/GNOME/tracker/-/jobs/442016 (runner: progress.gnome.org)
I suspect that it's something to do with IO on the osuosl.org runners. Perhaps there's something related to fsync() causing the tests to go slower than necessary.
