Fix SettingsContext error for Setup Component

[offstash]

When running Stash for the first time, after specifying the path in the Setup Component, the following error occurs:

Error: useSettings must be used within a SettingsContext

It seems like a problem that occurred in #4390
To fix this, I've added SettingsContext around StashConfiguration, but I'm not sure if it's in the right place.
If there's a better location, please let me know.

Closing in favour of #4527
