FetchCommunity: various fixes and improvements

[igor-sirotin]

Closes #4496
Closes #4496

Main changes

1. Temporal fix for bug: sort order ignored in store nodes waku-org/nwaku#2317 bug.
   I made the manager to always fetch all envelopes in the batch (no stop when community was found).
   These lines should be removed/reverted when the original bug is fixed:
   

   status-go/protocol/messenger_store_node_request_manager_config.go

   Lines 24 to 26 in fdcdec3

   	// TODO: remove these 2 when fixed: https://github.com/waku-org/nwaku/issues/2317
   	opts = append(opts, WithStopWhenDataFound(false))
   	opts = append(opts, WithInitialPageSize(defaultStoreNodeRequestPageSize))

   
   

   status-go/protocol/messenger_storenode_request_test.go

   Line 420 in fdcdec3

   s.Require().Equal(2, stats.FetchedPagesCount) // TODO: revert to 3 when fixed: https://github.com/waku-org/nwaku/issues/2317

2. Check if a desired community already exists in the database and require the fetched community Clock to be higher.
   If no newer information was fethed, nil is returned, even if the community exists in the database

3. Implement StoreNodeRequestManager options:

• WaitForResponse
• StopWhenDataFound
• InitialPageSize
• FurtherPageSize
  This allows a better control over the request. And made it possible to implement the fix (1) tidy.

4. It seems to me that the TestRequestMultipleCommunities is now less flaky, but still fails at about 1% cases.
4. UPD: Fixes TestRequestMultipleCommunities flaky test

5. Extracted DefaultMailserversByFleet function

6. Some other minor refactoring and logging

Test improvements

1. Added a mechanism to wait for the test store node to receive the envelopes.
   This was previously leading to bugs, the case is tested with TestSequentialUpdates

2. Implemented a test to check the fetched envelopes order: TestRequestCommunityEnvelopesOrder
   This is to address bug: sort order ignored in store nodes waku-org/nwaku#2317 bug, to ensure that our code behaves correctly (assuming that go-waku is also working correctly).

3. Implemented a TestFetchRealCommunity
   it allows to fetch community from all store nodes in a given fleet and check community state on each store node.
