* Allow merge of C_Cpp_Properties & configuration provider.

it looks like in [package.json line 5](https://github.com/microsoft/vscode-cpptools/blob/a62acdb5a52438540c266b409a0ee7f8e64f7a9b/Extension/package.json#L5), we add a suffix, "main", to the version. When we assign customers to target populations for experiments, we were trying to assign customers without any suffix to Public, which resulted in no one being included. Instead, I think we should be checking if the suffix is "main" and assign those customers to Public.

checking for undefined suffix, not just empty string
