Cannot partially extend config for deferred queries

[imp-dance]

Describe the bug
In version 1.0.5 - you cannot extend an existing loader and overwrite deferred: { shouldThrowError: true }

To Reproduce
Steps to reproduce the behavior:

1. Create a loader, and add config: { deferred: { shouldThrowError: true } }
2. Add deferred queries
3. Extend said loader, and add config: { deferred: { shouldThrowError: false } }
4. See error

Expected behavior
The loader should not throw when the deferred query fails.

Actual behavior
The loader does throw an error when the deferred query fails.
