[4.1.0] ignore active+enable when ensure is set to absent for systemd::timer

[mdc-webdb]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet:
• Ruby:
• Distribution:
• Module version: 4.1.0

How to reproduce (e.g Puppet code you use)

systemd::timer { 'foo.timer':
    ensure          => $foo,
    timer_source    => "puppet:///modules/${module_name}/foo.timer",
    service_content => template("${module_name}/foo.service.erb"),
    active          => true,
    enable          => true,
    require         => File[$foo_command]
  }

What are you seeing

When $foo are absent then this error:

Evaluation Error: Error while evaluating a Function Call, Can't ensure the unit file is absent and activate/enable the service at the same time

What behaviour did you expect instead

simple that when $foo are absent, that the timner+server are removed and the other options are ignored.

This has been done deliberately:

#122

ambition is to stop the service before the unit file is removed so forcing you to specify stop on unit removal makes sense.
