Try fixing DM creation in Maestro (#7204)

* Try fixing DM creation in Maestro

* Also handle 'invite new people to this room' with first invite to aRoomName

* Try adding a room list clean up sub-flow

* No need to press back button after successful invites

* Looks like 'hideKeyboard' works as 'back' and messes up with the navigation. Try using the workaround described in https://docs.maestro.dev/reference/commands-available/hidekeyboard#workarounds
