Show better errors when loading notifications fails (#3448)

* Show better errors with notification loading fails

The errors are returned as a JSON object, parse it, and show the error
message it contains.

Handle the cases where there might be no error message, or the JSON may be
malformed.

Add tests.

Fixes #3445
