Proxy exception messages are truncated
all proxy exceptions that uses the wrapped exception hide important information, and do not even log to the log file the full message.
looking at the code, I can't really see any usefulness to the WrappedException class? maybe it should be removed?
Fixes #13599 - Wrapped exception truncate moved to client
Removed message truncation from server side, and moved it to client
side - the message is truncated with ellipsis. On mouse over full
message is presented as popover.
This commit required a small change to `data-ajax-url` handler in client
to enable proper tooltip presentation in HTML loaded by AJAX.
