Apollo Angular SSR use state transfer: not respect default cache policy `cache-first`, have to add manual on each request

[hiepxanh]

Describe the bug

As Apollo Client describe, it default policy is cache-first which is not really understand why not working on apollo angular universal if I use TransferState.

To Reproduce Steps to reproduce the behavior:

• add SSR and apollo-angular Store rehydration#
• make request, it cached on server, check the request, it still make the request to server on client again.
• console.log(this.apollo.client.cache.readQuery(query)) can see the cache result still here.
• add cache-first to the query. Client apollo happy now and don't make request.

Expected behavior

• I do not need to add cache-first on every request. I don't know is that by design or miss take. the Apollo Angular change it? if it by design. we should note the developer. "You should add fetchPolicy: 'cache-first' if you want your query read the cache from on the document.

Environment:

dependencies:
@angular/cli 13.1.2
@angular/core 13.2.1
@apollo/client 3.5.8
apollo-angular 3.0.0
graphql 15.8.0
typescript 4.5.4

Additional context

I'm willing to check source code. I already look in source code and don't find that Apollo Angular change anything relevant to fetchPolicy. I still cannot find the reason. I can make a PR which have some test case if you like. or an other PR for document if you think we need notice developer should add cache-first if you want to cache. BTW, what is the default cache policy of Apollo Angular? did I miss something?
