Random panics

[shackra]

I was generating mocks for some modules in my project, and I noticed that mockigo panics when there are already files named with _test.go (or so I believe this has to do with the panics)

➜  mockigo --test-pkg --gogen
panic: runtime error: invalid memory address or nil pointer dereference [recovered]
        panic: runtime error: invalid memory address or nil pointer dereference

maybe is something in Go 1.22 causing this problem?
