Backports the following commits to 7.x:

Fixes elastic#71461 regression since 7.7

New state syncing utils didn't properly handle errors,
Errors happening during URL parsing or writing wasn't handled, so state syncing could stop or in worth case blow out. (see elastic#71461)

There are not much scenarios where missing proper error handling could really impact users, except the one described in elastic#71461:

Kibana users state:storeInSessionStorage
Users often intuitively share hashed dashboard urls directly
When someone opens those urls - there is a blank screen with warning
In 7.6 - dashboard would still load with default state.
Since 7.7 these still could be achieved by removing query params for URL, but it is not obvious for regular users.

This PR makes sure that behaviour is similar to one we had before 7.7.
