fix js error when clicking home button on mobile sidebar

[e-five256]

prior to this, clicking on the home button in the sidebar generated the error:

Error invoking action "click->options#home"
Error: Action "click->options#home" references undefined method "home"

this is because no home action exists in https://github.com/MbinOrg/mbin/blob/main/assets/controllers/options_controller.js
the button still functioned, however, so functionally this changes nothing, just wanted to clean up the js exception
