This field was deprecated in March last year and was removed November
last year. Before this change any user subcommand just failed. Will be
adding some integration smoke tests to catch these sort of issues.

Additionally found one place we didn't set Content-Type which
Sourcegraph also recently started enforcing.

* update GraphQLErrors to have constructor + handle paths

* add test for repo list with some repos failing but not all

* update src repo list to handle graphql errors

 - errors are treated as warnings when getting partial data
 - if we have no data and just errors that is a fatal error

* add comment

* Handle partial repo list warnings
