Fix: resending messages while clicking error callout

Description

• Provides retry for all messages in the chat if user clicks Click to retry in error callout, if messages are not empty array and if state.chat.error contains the error message (so in that case we can say, that this error is from the chat itself, not from somewhere else in the app)
• Note: Tested with erroring integration config files. If error is permanent, then this retry will not get rid of error. This fix will give the simplification of user flow by minimizing amount of steps to get chat working after error message has appeared.
• Bug - When press "Click to retry" last message is deleted and last but one message is re-requested
