[AO] Handle buildEsQuery error (such as leading wildcard) in status change (#159891)

Fixes #159079

## Summary

In the case of providing a wildcard in the search query, an error might
be generated depending on whether the related setting is enabled or not.
This PR tries to handle this error on the Alerts page for a better user
experience.
