Inconsistent mesh mapping schemas metadata into elastic

## Gentics Mesh Version, operating system, or hardware.
- v1.3.2

## Operating System
- Windows

## JVM
- Open JDK 11.0.5

## Problem
Currently I'm working by using raw queries to elastic search, in order to have some filters I need to select which schemas I want, therefore I use the schema.name property that mesh creates by default, the problem is that sometimes its mapping differs from schema to another, I'm talking exclusively about metadata such as schema object.

Here's an example

## Expected behaviour and actual behaviour
Mapping schemas metadata equally among all indices.
