If a test calls os.Exit, go-opine fails to report on the entire file

[lexrj]

Minimal example:

func Test_exits(t *testing.T) {
	require.NoError(t, errors.New("Test"))
	os.Exit(1)
}

Adding any other tests to the suite shows that the entire file is excluded from the test report, while go test -race ./... will still report them, and also throw a moderately useful error including the test name:

--- FAIL: Test_exits (0.00s)
    daemon_test.go:12:
        	Error Trace:	daemon_test.go:12
        	Error:      	Received unexpected error:
        	            	Test
        	Test:       	Test_exits
flag provided but not defined: -test.testlogfile

(and then prints the usage)
