[Bug] Fails to run `GoTest*` when using gotestsum as runner

[protiumx]

Using test_runner = 'gotestsum' and running any if the GoTest* commands fails due to a test parameter added to the command to run gotestsum test ./folder, gotestrun does not accept tests as parameter. Probably coming from here https://github.com/ray-x/go.nvim/blob/master/lua/go/gotest.lua#L190 and other places
