Touch plugin enabled

The <enable> tag is not enabled. I tried to set it to false but it always enabled.

This condition is always achieved.
I think the problem is with Get<bool>

Oof, yeah that should be _sdf->Get<bool>("enabled", false).first. Mind creating a PR?

I tried to edit the workspace/src/sdformat/include/sdf/Element.hh but it didn't work. Is this the write file?

I meant line 188 https://github.com/ignitionrobotics/ign-gazebo/blob/deaa059e7a82e177279343de125c39b44f09237a/src/systems/touch_plugin/TouchPlugin.cc#L188. second should be first.

Get returns a std::pair where the first value is the actual value of the sdf parameter and the second value indicates whether the parameter was set.
