Bugfix from parameter

For evaluation, Theodolite queries Prometheus for data related to a specific experiment. For that, Theodolite specified from and to parameters. Setting the from parameter before the setup() is done, can cause an incorrect query range and an incorrect warmup period, for experiments which takes a long time for the startup phase.

For that reason, the from parameter should be set after the setup() is done.
