msi: configure OpenVPN Service also on reinstall

We configure openvpn service (set startup mode and run, if needed)
only on installation or upgrade. This is achieved by running
configuration custom action with "NOT Installed" condition.

However the product may be reinstalled (even though we disable it in UI),
for example when pushed via AD Group Policy or with command line

    msiexec /fomusv "OpenVPN-2.6.2-I001-amd64.msi" /L*V reinstall.log

In this case OpenVPN service status is set to "disabled", since our
configuration custom action won't be run.

Fix by changing action condition to NOT REMOVE, which covers both
install/upgrade and reinstall cases.

Fixes #348
