GET_VARIABLE macro crashes when "printer." is left in

[ghoudy2shoes]

When debugging a macro that gets a variable I just want to copy paste the whole variable (example: GET_VARIABLE NAME=printer.toolhead.homed_axes) but that will fail unless you manually remove the start (GET_VARIABLE NAME=toolhead.homed_axes).

To fix it I added these few lines right after the variables are set.

    {% if names|first == "printer" %}
      {% set names = names[1:] %}
    {% endif %}
