Ashod Nakashian 42f5ceae42 wsd: test: improvements
This reduces the execution time of some
long-running tests and improves stability.

A full debug build of Core and Online
now finishes on my machine in under 3 minutes,
down from slightly over 4 minutes. A significant
saving when running the tests frequently and
repeatedly.
