Filters.eq().not() is not applying the negation (2.0.2)

[DefiantCatgirl]

When building a query such as

.filter(eq("isDeleted", true).not())

the resulting query to the database is isDeleted: true and not $not: {isDeleted: true}. I know $ne exists so this kind of query shouldn't normally be used in the first place, but I accidentally had some in the codebase.

Presumably because this instantiation ignores checking the not in the overridden function.

    public static Filter eq(final String field, final Object val) {
        return new Filter("$eq", field, val) {
            @Override
            public void encode(final Mapper mapper, final BsonWriter writer, final EncoderContext context) {
                writer.writeName(field(mapper));
                writeUnnamedValue(getValue(mapper), mapper, writer, context);
            }
        };
    }

you're exactly right. I'm going to mark this as a 2.1 since that should be out in a few days and I'm trying to avoid a 2.0.3. But I can backport if a 2.0.3 is needed. thanks.
