Change toThrowGqlError message failure to support asymmetric matchers

Missed in #3183

This previous code avoided quoting the message string.
I was trying to reduce syntax to sort through in error message.

Compromising to include quotes here to be consistent & support the matchers.
```
Message:
  StringMatching: /not found/
  "Server Error"
```
```
Message:
  "Not Found"
  "Server Error"
```
