Block shortcut to run itself

[GewoonYorick]

Adding a shortcut with the same name and command to execute creates a loop which crashes thelounge.

We could just block all commands that have the same "to" as name.

Personally I run znc behind thelounge with the *alias module loaded, this allows to to run aliased the commands from different clients aswell. So it'd be nice if those could be registered in the plugin so they appear in the pop up menu when typing / (hence name and the to is the same)

the log:
/home/thelounge/.thelounge/packages/node_modules/thelounge-plugin-shortcuts/index.js:45
return shortcuts.some(function (o) {
^
