[Minor] "Place solution and project in the same directory" checkbox breaks creation of new project

[Antonytm]

Create button doesn't work, when Place solution and project in the same directory is checked.

As Place solution and project in the same directory has no sense for Helix Solution project it is minor. But it is confusing when you accidentally forgot about the checkbox and wonder why Create button doesn't work. That is why it will be enough some information message about it.
