[Discover] Invalid time range given by URL causes Exception

[kertal]

Kibana version:
7.0 - 8.0 (Master)

Describe the bug:

Depending on the version of Kibana, from 7.0 upwards, an invalid time range provided by the URL can cause a range of problems. So if the URL provides e.g.time:(from:'',to:''):

Kibana 7.0 - 7.7 submits this request, setting those values to null, which means, that all records are queried (which can lead to performance peaks).

Kibana 7.8 displays an error message, doesn't submit the request, which is better, but the message could be more helpful

In our current development version, the request isn't submitted, but causes an exception, that's why I labeled it as blocker:

Steps to reproduce:

1. Open Kibana with Discover,
2. Select an index pattern with time field,
3. Set a custom time range in UI
4. Modify the URL in the Browser setting from to to '', the part of the url containing the time range should look like this: time:(from:'',to:'').
5. Reload the Browser Tab.

Then you should experience the described issues.
