Stream shouldn't apologise when there are no records

Bug Report

Expected Behavior

When there are no records to show, the messaging to the user should be clear.

Actual Behavior

Stream apologises to the user: Sorry, no activity records were found. It's a small issue but there is no reason for Stream to apologise here, and for a non-native English speaker this message may not be clear and may suggest there was a problem fetching the records, when in fact everything is working as expected.

I recommend that the Sorry prefix is removed from this phrase to enhance the clarity.

Steps to Reproduce the Problem

1. Clear your Stream database from the Stream -> Settings -> Advanced menu
2. View the activity log
3. See an apology
