Move prompt gathering out of GetSessionDetails

When I introduced the concept of gathering session details after each command that gets run, I rolled prompt gathering into that to avoid running yet another command each time a prompt is needed. It seems that this causes more problems than necessary because a prompt function that throws errors does not get handled correctly anymore.

I'll move prompt gathering back out into the ConsoleService so that we can check for errors and return a default prompt appropriately.

まず GetSessionDetails と ConsoleService を見つけ、次に prompt の収集と prompt 関数のエラーがどこで処理されているかを追跡します。prompt の収集を ConsoleService に移し、issue に記載されているとおり、prompt のエラーによってデフォルトの prompt が生成されることを確認します。
