Vladyslav SimonenkoandGitHub 1e35ad9f2b Break out of pagination in scavenger on errors (#8133)
## What changed?
Break out of the loop, when iteration through mutable states fails

## Why?
Previously, we continued to iterate, leading to the panic:
https://github.com/temporalio/temporal/issues/8037

## How did you test it?
- [X] run locally and tested manually
- [X] added new unit test(s)
