correct bootstrap

Fixes a few things:

* Configure::load('app.local.php', 'default'); is invalid as it tries to load "app" plugin files.
  " Fatal error: Uncaught exception 'Cake\Error\MissingPluginException' with message 'Plugin app could not be found.'"
  I suggest using app_local syntax instead.
* Also moving it out of the try catch block as that part and its error message is cloaked by the catch block.
