[Task] Updates with notifications should account for current error

[tthvo]

Right now, if their is an error view, notifications will continue to update the table without considering the current error.

For example:

1. Have 2 tabs open for Cryostat web console. Both use Browser Session settings for credentials.
2. Connect to a target that requires credentials on both tab.
3. Enter credentials on one tab and close the modal on the other (display error view).
4. Create a new recording on the tab with valid credentials.
5. Tab with error view does not update but receives notification. However, if you click on toolbar filter, you can see data (i.e. name, labels, ...) of the new recording.

I guess the question is should these notifications pop up at all when error view is shown?
