Got an answer from this post !

Inside platforms/android/cordova/lib/emulator.js :

Change:

return superspawn.spawn('android', ['list', 'avds'])

To:

return superspawn.spawn('android', ['list', 'avd'])

Change:

var command = 'adb -s ' + target + ' install -r "' + apk + '"';

To:

var command = 'adb uninstall "' + pkgName + '"; adb -s ' + target + ' install -r "' + apk + '"';
