Title: close last used ssh connection after test

This fixes an issue i had with multiple test files in `t/`.
If you have multiple test files, the existing connections are not closed in Rex::Test::Base finish(). That causes Rex to run the following `virsh list --all` commands on the existing SSH connection and the tests after the first file are failing silently, as Rex is unable to get the list of the virtual machines.
