requirements-swh: Bump requirements to fix webapp build
That fixes the build [1] to unstuck @anlambert.
I'm not entirely satisfied though but i don't see how to fix it otherwise. I don't really get what's pulling this (I see nothing explicitely requiring something from the core.db...).
swh-core!175 (closed) (included in swh.core 0.6.1) does introduce the new postgresql_fact
fixture factory (to make pg db tests using the built fixture ouf of that
factory faster). Which pulls the pytest_postgresql as runtime dependency...
