test warm start

[visr]

We've tested in the past that two runs that follow each other, are exactly equal to a single run of that period without restart. This was to verify that the state handling was working as intended. This test was done offline, and is not yet part of the automatic tests. We should convert the snippet below to an automatic test to verify the state handling code stays correct.
