fix: invalidate query cache when creating custom storage volume [WD-1…

…3879] (#829)

## Done

- Previously we did not invalidate the query cache for custom volumes
when creating a new one. This means when a user navigate back to an
instance and try to attach the volume, they will not see the volume in
the select modal unless if they refresh the page. This PR resolves this
issue.
