Integrations override table: Don't show empty state when error occurs
The following discussion from !66995 (merged) should be addressed (related to #218252 (closed)):
- 
@pslaughter started a discussion: issue (non-blocking): If there's an error fetching the first page of projects we show the "empty-text" which is a bit misleading. Ideally we would just show the user that something went wrong and enable them a way to refresh. Could/should we create a follow-up for this? 😄 
Possible approaches:
- Use a gl-alert, placed under the tabs, and hide the table altogether.
