Description

[ISHIKAWA, Chiaki]

I have been running |make mozmil| test suite of C-C thunderbird (FULL
DEBUG BUILD).

I noticed the error in the log:
System JS : ERROR (null):0 - uncaught exception: This login already exists.

The  error occurs during testing of
TEST-START | /REF-COMM-CENTRAL/comm-central/mail/test/mozmill/newmailaccount/test-newmailaccount.js | test_restored_ap_tab_works

and is is preceded by the following lines.

I think 

 - the code should catch the exception, and

 - the test suite itself should catch this condition and flag this
   test as failed since it uncovered a major problem.
   (Now, it is passed as success.

TIA
