Review Comment:
I changed a bit this test to use separate external RO-tx here. And test
fails here with
```
Caused by: org.apache.ignite.internal.tx.LockException: IGN-TX-4 Failed to
acquire a lock due to a possible deadlock
[locker=019811d2-7bc3-0000-2722-841700000001,
holder=019811d2-7b6f-0000-2722-841700000001] TraceId:789c7be0
```
On the main branch such case passes.
Is it ok?
Full test case
```java
@Test
void testExplicitTransactionKvCase() {
IgniteClient client = client();
IgniteSql sql = client.sql();
sql.execute(null, "CREATE TABLE my_table (id INT PRIMARY KEY, val
INT)");
// First, let's fill the table and check every row in implicit tx.
// This should also prepare partition awareness metadata.
int count = 10;
for (int i = 0; i < count; i++) {
try (ResultSet<?> ignored = sql.execute(null, "INSERT INTO
my_table VALUES (?, ?)", i, i)) {
// No-op.
}
}
for (int i = 0; i < count; i++) {
try (ResultSet<SqlRow> rs = sql.execute(null, "SELECT * FROM
my_table WHERE id = ?", i)) {
assertEquals(i, rs.next().intValue(1));
}
}
// Now let's clean the table and do the same steps but within
explicit tx.
try (ResultSet<?> ignored = sql.execute(null, "DELETE FROM
my_table")) {
// No-op.
}
Transaction tx = client.transactions().begin();
Transaction tx1 = client.transactions().begin(new
TransactionOptions().readOnly(true));
for (int i = 0; i < count; i++) {
try (ResultSet<?> ignored = sql.execute(tx, "INSERT INTO
my_table VALUES (?, ?)", i, i)) {
// No-op.
}

my_table WHERE id = ?", i)) {
