Calling GET /api/v1/budget_limits fails when (I think) no budgets are available

[miyoyo]

Bug description
I am running Firefly III version 4.7.6.2

Calling the budget_limits endpoint, possibly when no budgets exist (I don't have any) results in an error.

Steps to reproduce
(Maybe?) Have no budgets
Send a simple, authenticated GET request to /api/v1/budget_limits

Extra info
I was using postman as an API caller.
Here's my uname -a:
Linux -Redacted- 3.16.0-5-amd64 #1 SMP Debian 3.16.51-3+deb8u1 (2018-01-08) x86_64 GNU/Linux
