API: revive unit-tests

[olof-nord]

There are currently nine unit tests in three files which do not compile.

• api/comment_approve_test.go
• api/comment_delete_test.go
• api/comment_vote_test.go

Before we can automatically run tests within a CI, we need to add the missing arguments to the tests.

$ GO111MODULE=on make test               
GO111MODULE=on go mod vendor
go test -v .
