Description

Using a generic type as a QueryEntity value type results in a broken SQL table name:

            var ignite = Ignition.Start(TestUtils.GetTestConfiguration());

            var cfg = new CacheConfiguration(
                TestUtils.TestName,
                new QueryEntity(typeof(int), typeof(GenericTest<string>)));

            var cache = ignite.GetOrCreateCache<int, GenericTest<string>>(cfg);
            cache[1] = new GenericTest<string> {Prop = "1"};

            var tables = cache.Query(new SqlFieldsQuery("SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES"))
                .Select(x => (string) x.Single()).ToArray();

Resulting table name is 0, CULTURE=NEUTRAL, PUBLICKEYTOKEN=7CEC85D7BEA7798E]].
We should add .NET generics support to org.apache.ignite.internal.processors.query.QueryUtils.typeName.
