BUGFIX: testSequence is a bit more delicate with the new randomizer

testSequence is by default the main one specified for an experiment.
If we are using the user-specific test sequences, after loading the
default, we have to switch over to the user-specific ones.

This bug was caused by not switching over early enough.
