Relay compiler doesn't show code excerpt when there is only one error

[andrehsu]

When there are two errors, relay-compiler shows the code excerpt

ERROR:
Encountered 2 errors:
- Unknown argument 'emailId' on field 'setEmailPrimary' of type 'Mutation'.

  components/Emails/EmailList.tsx:3:29
  2 |         mutation EmailList_setPrimaryEmailMutation($emailId:String!){
  3 |             setEmailPrimary(emailId: $emailId){
    |                             ^
  4 |                 emailId
- Unknown argument 'emailAddress' on field 'addEmail' of type 'Mutation'.

  components/Emails/Emails.tsx:3:22
  2 |         mutation EmailsAddEmailMutation($emailAddress:String!, $userId:String!) {
  3 |             addEmail(emailAddress: $emailAddress, userId:$userId){
    |                      ^
  4 |                 emailId

When there is only one, it doesn't show the excerpt

ERROR:
Unknown argument 'emailAddress' on field 'addEmail' of type 'Mutation'.

The second form isn't really helpful since it doesn't tell me which mutation/query is causing the issue, nor which file the error is located in.

Relay version 10.1.2
