Can't start new chat with no extensions

If all extensions are disabled when starting a new chat it will forcibly change to the set of default extensions or, if there are no default extensions enabled, a "Scheduler" extension that isn't normally visible in any menu in the app. My guess is that the implementation is replacing an empty set of extensions with the set of default extensions and that an empty set of default extensions is replaced with a set containing only the "Scheduler" extension. If this is the case, then fixing the former should fully resolve this issue, though the latter should be fixed anyway since it is still an error.

In short, empty sets of extensions explicitly set by the user are not respected and might be being interpreted as default values or an absence of user setting.
