fix ToggleSameIds that calls SameIds with no args

[110y]

ToggleSameIds is causing an error that says Not enough arguments for function: go#guru#SameIds.
So, I fixed it.

I'm glad if someone reviews this, thanks.

CI failed with this error:

--- FAIL Test_goimports (0.022243s)
        function Test_goimports line 13: Expected 'package main\n\nimport (\n\t"fmt"\n\n\tlogging "gh.com/gi/foo-logging"\n)\n\nfunc Foo(log *logging.TestLogger) {\n\tlog.Debug("vim-go")\n}\n\nfunc main() {\n\tfmt.Println("vim-go")\n}' but got 'package main\n\nimport (\n\t"fmt"\n)\n\nfunc Foo(log *logging.TestLogger) {\n\tlog.Debug("vim-go")\n}\n\nfunc main() {\n\tfmt.Println("vim-go")\n}'

But, I think this error was caused by recently goimports update including breaking changes and this pull request isn't related.
