Not using settle in all cases causing unexpected behaviour

transformError(error, reject, config)

settle is not used in the fail handler, causing inconsistent behavior.
The isAxiosError is missing now.

The suggested way to fix this is instead of creating a separate handler as we do in transformError, we create a dummy error response and pass it into the settle function.
