AttributeError: 'NoneType' object has no attribute 'get_function_at'

As a result of this, only the very first struct (ACL) was actually pushed by BinSync; everything else was lost.

Steps to reproduce the bug

1. Open this BNDB.
2. Click Analysis -> Import From BNDB.
3. Import all types (structs, typedefs, enums) from this BNDB.

Environment

• Binary Ninja 3.5.4322-dev Personal (94049b27)
• BinSync 3.13.1
