Closing context switching window when choosing context

[i-interprete-on-the-fly]

Description

This is kind of related to #492. Currently the context switcher window stays open after selecting a new context which is opened in the background. For me a more intuitive behavior would be that the switcher window closes and does not have to be closed with ESC afterwards. This is just a minor issue but does impact the smoothness (imo) negatively. I understand that this may not be desirable if users want to peek into their contexts without leaving the context switcher. So this is just a suggestion I would be happy to discuss
