Double quote arguments when execute the expect script

[planecore]

In order to be able to pass variables that include spaces, I double quoted the arguments.

Hello,

Thank you for your pull request. I saw that "server_name" as some constraint (3 - 15 letters or digits). I merge it because it's a good practice. But in this case it's not really usefull because no variable should have a space.

Got it. I sent you another log in my issue, can you check it please?
