[CI] Random test failure with test_loadReplies_whenIsFirstPage_shouldClearCurrentMessagesExcludingLocalOnly

[laevandus]

🎯 Goal

test_loadReplies_whenIsFirstPage_shouldClearCurrentMessagesExcludingLocalOnly sometimes fails on CI with

XCTAssertEqual failed: ("1") is not equal to ("3")
[07:04:25]: ▸ Test Case '-[StreamChatTests.MessageUpdater_Tests 

I think it is related to timing in that test where we modify data using writableContext and then expect DTOs created using the view context to update immediately.

📝 Summary

• Read data from DB every time when asserting
• Add convenience read methods
