Summary

Build systems do not check whether or not their target commands are enabled.

Expected behavior

Actual behavior

Steps to reproduce

With a build system as follows:

{
    "cmd": ["cmd"],
    "target": "target"
}

and a target command as follows:

import sublime
import sublime_plugin

class TargetCommand(sublime_plugin.WindowCommand):
    def is_enabled(self, cmd=None):
        return False

    def run(self, cmd=None):
        print("TargetCommand ran with %s as the argument." % cmd)

running

>>> window.run_command("build", {"build_system": "Packages/Package/BuildSystem.sublime-build"})

produces

TargetCommand ran with ['cmd'] as the argument.

as output in the console.
