Transaction errors are never displayed in database query view

[Adam Roben (:aroben)]

Transaction errors are never displayed in database query view.

To repro:
1. Go to http://webkit.org/misc/DatabaseExample.html
2. Go to the Databases panel and click on the NoteTest database
3. Enter the following text on the query input line:
INSERT INTO WebKitStickyNotes (note) VALUES (NULL)

Results:
The line of text you entered disappears, and no error is shown.

r=me; seems fine as is

But this seems a little strange to me. Why wouldn't we instead use two different error functions for the two different cases, and then share a common worker function?

Yeah, that's probably a better way to go. I guess this patch is a little too quick-n-dirty.
