Errorf not finishes test execution

[DifferentialOrange]

We use t.Errorf in tests, for example

go-tarantool/uuid/uuid_test.go

Line 56 in bec9f72

t.Errorf("Failed to connect: %s", err.Error())

It seems that by design t.Errorf do not stops test function execution, but it is expected in tests:

package main

import (
	"testing"
)

func TestEverything(t *testing.T) {
	a := "sdf"
	if a == "sdf" {
		t.Errorf("end")
	}
	t.Errorf("end 2")
}

=== RUN   TestEverything
    prog.go:10: end
    prog.go:12: end 2
--- FAIL: TestEverything (0.00s)
FAIL

Program exited.

Documentation says:

Errorf is equivalent to Logf followed by Fail.
Fail marks the function as having failed but continues execution.

We should use Fatalf(doc) or explicit returns where it's expected.
