'error' value not updated after correct next result received

[gbouteiller]

Describe the bug
When an error occurs on useQuery and then a result is received afterwards, the error reference is not updated.

Use case
I get an unauthenticated error during an anonymous query and I expect the error to be gone after login. The result is correctly set but the unauthenticated error is still set.

Expected behavior
error should be set to null after a correct next result.

Versions
vue: 2.6.11
vue-apollo: 4.0.0-alpha.4
apollo-client: 2.6.8

Additional context
It seems like the error value is only updated in the processError function if an error occurs but never reset.
