[FIX] Invalid regex on search fields crashes UI

[heitortanoue]

Problem to be solved

Admin -> Workspace -> Users entering ? or another invalid regular expression into the search blank crashes the UI instantly.
Other Admin pages with Regex searches have shown the same error:

1. Custom Emoji
2. Custom Sounds
3. Custom User Status
4. Integrations

Acceptance criteria

These search fields should accept valid RegEx and regular text, but showing an error message when an invalid input is given.

Is there a possibility we could use
import { escapeRegExp } from '@rocket.chat/string-helpers';
instead of testing the regex? I think this would ensure no regex would break ever...

[hugocostadev]

I agree with @gabriellsh , there is a setting that you can change the accepted chars in the username, because of that we don't have to restrict the search for certain chars.
