MemoryMap UI fails to find malformed section names when attempting to open the context menu

[loganjchris]

Version and Platform (required):

• Binary Ninja Version: 5.4.9784-dev personal
• Edition: Non-Commercial
• OS: Arch Ubuntu Linux
• OS Version: 7.0.11-arch1-1
• CPU Architecture: x64

Bug Description:
Please provide a clear and concise description of what happened.

Steps To Reproduce:
Please provide all steps required to reproduce the behavior:

1. Open a malformed binary with invalid section names
2. Try to use the MemoryMap sidebar or Pane UI view to edit the section by right clicking
3. Log output shows an error finding the section name. I was able to use the python API to view the section information, remove the auto sections, and add new user defines ones.

Expected Behavior:
Would like to be able to use the context menu to edit the section attributes when malformed binaries use custom/invalid section names

Screenshots/Video Recording:

Let me know if more information or the binary is needed
