I've noticed find references/code lens were broken for indexer properties, in a similar fashion to #1371. Yet this couldn't be fixed by pushing "CanBeReferencedByName" mess any more, as both get/set method and indexer property can't be referenced by name. So the PR would make sure:
Locations of usages returned by Roslyn are used as-is
When request wants locations of definitions to be added to the response, get/set methods of properties are filtered out using this. Works for both normal and indexed properties and add/remove of events . This perserves current behaviour, but removes all of the unintented side-effects.
There is a new test for indexer properties.
