chore: slightly improve logging of failed OAuth flow

Description

Small fix to catch an error during the createOAuthAccountFromCode() call.

Before

2024-03-04T14:33:29:329 [debug]: fetch: request to https://gitlab.steveazz.xyz/oauth/token returned HTTP 401 after 354 ms

After

2024-03-04T14:24:41:413 [debug]: fetch: request to https://gitlab.steveazz.xyz/oauth/token returned HTTP 401 after 354 ms
2024-03-04T14:24:41:424 [error]: OAuth flow: Creating account from code failed:
