Swap the open and configure error reporting in the terminal example

It seems they were accidentally misplaced, and it was not caught by anyone while
testing and using this example. Although, I have seen users doing this mistake
on Stack Overflow, so I was wondering where they would get the idea from. It is
possible they have done such mistakes due to a copy/paste operation from this
old example.

Obsolete the "settings restore on close" API

Now that the settings detection is removed, it would be better to make this API
deprecate because it does not make much sense anymore. It was a bad idea to add
this, but we cannot remove it for now, hence the obsoletion.
