[Process] Use assertSame instead of assertEquals to avoid comparison against `null`
[Process] Fix process status in TTY mode

When running a process with TTY mode, status in automatically set to `terminated`
once it's started.

It's wrong for two reasons :
 - The status of the process is not yet terminated.
 - The exitcode value is never caught

Use identical comparison instead of equal. In case the exitcode has not been caught, `Process::isSuccessful` returns true instead of false. It should not happen, but it's much more clean like that.

I need exception message to be checked more accurately in my upcoming PR about windows.
I decided to make a separated PR as the other one will probably take some time before being merged

This is a minor error ; creating the process must be delegated to the implementation

[Config] XmlUtils::convertDomElementToArray does not handle '0'

`XmlUtils::convertDomElementToArray` does not handle `0` as a value of a text node, and interprets it as `null`.
