cmd/go: fix errors for commands run outside of modules

Since CL 148517, several commands (including list and get) work when
GO111MODULE=on even when no go.mod file is present. This broke an
assumption made by "fix" and "generate" which caused panics when run
with a list of .go files (whether or not the command was run inside a
module).

This change fixes those assumptions and adds test cases for other
commands run outside modules.

Fixes #29097
