SRU tracking bug for 1.3.3~13.04

[Dmitry Shachnev]

I have uploaded unity-mail 1.3.3~12.04 to raring-proposed.

== Changelog / Development fix ==

This is a no-change backport of the version in saucy:

unity-mail (1.3.3) saucy; urgency=low

  * New bugfix release.
    - Prevent potential crash in check_email when email is not valid.
    - If the default collection does not exist, try to create it. This
      really fixes the ItemNotFoundException problems (LP: #1165548).
    - Fix the version number in the help message.

Diff between 1.3.2 and 1.3.3: https://launchpadlibrarian.net/139404531/unity-mail_1.3.2_1.3.3.diff.gz

== Impact ==

This fixes a major issue (bug 1165548, currently also crash №1 for unity-mail on errors.ubuntu.com) when it crashes when the default Secret Service collection doesn't exist, and two minor issues.

== Test case ==

Please see test case for the ItemNotFoundException in the bug 1165548.

Test case for the "Fix version number in the help message" part:

1. Run "unity-mail --version" command.
2. The output should be "Unity Mail, version 1.3".

== Regression potential ==

No regression potential (given that the new behaviour is tested on systems both with and witout the default keyring).
