Fix the vmnames in time_manage test

This test relies on outdated first vm name, while there is "main_vm"
parameter pointing to the correct name. Also it stores all created
vmnames, but instead of relying on this variable it tries to create the
name in later loops.

Ideally one would store the actual vm objects, but let's use this as a
hotfix.
