Memory leak in FieldResolver

[alwag85]

NEST 2.0+:

If Nest.Field was created by LambdaExpression then MemberExpression.GetHashcode() used as Hashcode for dictionary FieldResolver.Fields, but method GetHashcode has not overridden in MemberExpression and used Object.GetHashcode().

👎 us first for missing the issue when initially reported and second for introducing this in the first place 😢

We will get this fixed today and put an update out on nuget.org

Just pushed new versions of Elasticsearch.Net and NEST to nuget with a fix for this.

Thanks again for reporting 👍
