Crash when calling demangle_generic with None as mangled_name parameter

[Lidenburg]

Version and Platform (required):

• Binary Ninja Version: 5.2.8722 (stable) and 5.3.9139 (dev)
• Edition: Non-Commercial
• OS: Ubuntu Linux
• OS Version: 22.04
• CPU Architecture: x86_64

Bug Description:
Running the python one-liner demangle_generic(bv.arch, None) causes binary ninja to crash.
The following is the stacktrace from 5.2.8722 (stable):

$ ~/binaryninja/binaryninja `which ls`
Terminating with uncaught exception
Here's a stack trace (hopefully):

Steps To Reproduce:

1. Open any binary (tested with arm binaries and x86_64)
2. open the python console
3. type demangle_generic(bv.arch, None)
4. Binary Ninja crashes

Expected Behavior:
Binary ninja should not crash.

Screenshots/Video Recording:

Binary:
Any binary should work. Tested against x86_64 ls.
