go-test-current-test doesn't work if the current test is part of a testify test suite

[jguenther]

If point is in a test that's part of a testify test suite, go-test-current-test fails with an error:

$ go test -m TestSomeTestInASuite\$ .
flag provided but not defined: -m

After playing around with it, it seems to work just fine if I change -m to -testify.m:

$ go test -testify.m TestSomeTestInASuite\$ .

Although this testify issue suggests that the correct command would be:

$ go test -run TestThatCallsSuiteRun -testify.m TestSomeTestInASuite\$ .

Where TestThatCallsSuiteRun is the function that calls suite.Run() with your test suite struct type.

But it seems like at least for go 1.10 and the latest version of testify, it works with just -testify.m without -run.
