Update indexes fails if there already exists same index with different name.

Bug Report

Running the doctrine:mongodb:schema:update command fails with error Index with name: <index_name> already exists with a different name if there already exists an index with same keys and options but different name on the collection.

Q	A
BC Break	yes
Version	2.1.2

Summary

Because name of an index is ignored when checking if index should be dropped in SchemaManager (PR https://github.com/doctrine/mongodb-odm/pull/2114) and because mongodb prevets creating duplicate indexes with different names, running schema update after renaming index can lead to failure.

Current behavior

Schema update fails with Index with name: <index_name> already exists with a different name.

How to reproduce

• Create entity mapping with an index
• run doctrine:mongodb:schema:update
• rename the index in the mapping
• run doctrine:mongodb:schema:update

Expected behavior

Drop the existing index, create a new one with the correct name.

I can offer my help on our Slack's #mongodb-odm channel but otherwise I don't know when I'll be able to look into the fixing the issue personally.
