Don't flush manifest in test bootstrap for performance reasons

Leave the decision to the phpunit.xml config (via <get> setting),
or to the individual run via "phpunit <folder> '' flush=1".
Flushing takes multiple seconds even on my fast SSD,
which greatly reduces the likelyhood of developers adopting TDD.
