Version and Platform (required):

Binary Ninja Version: 4.2.6541-dev
OS: Mac
CPU Architecture: M2

Bug Description:
After undefining a type, it persists in the IL (even across reanalysis).

Steps To Reproduce:

Open any binary
Define a user type struct
Set that type on a variable (struct* or struct)
Undefine the struct

Expected Behavior:
The type of the variable should be reset to whatever the auto type from analysis was.

Screenshots/Video Recording:

Josh tested this in 4.1 and 4.0 and was able to repro it.
