.Net MethodVisitor ambiguous exception during get StringMethod "Contains"

[Tâm Nguyễn Mạnh]

Hi,

There are more than 1 Contains method for string, that lead into Ambiguous
exception

modules\platforms\dotnet\Apache.Ignite.Linq\Impl\MethodVisitor.cs:57
``` C#
GetStringMethod("Contains", del: (e, v) => VisitSqlLike(e, v, "'%' || ? ||
'%'")),
```

I think it should be:
``` C#
GetStringMethod("Contains", del: (e, v) => VisitSqlLike(e, v, "'%' || ? ||
'%'"), argTypes:new []{typeof(string)}),
```

Thanks & Best Regards
