my_activity.py: Fix to work with non-ascii characters

The default encoding for python 2.7 strings is ascii.  Some of
the titles of issues, such as http://crbug.com/477941, contain
non-ascii characters, and cause my_activity.py to throw an
exception.  Re-encode the unicode title string to ascii with
the 'replace' option, to replace non-ascii characters with '?'.

R=maruel@chromium.org
BUG=none
TEST=Run `my_activity.py` with #477941 in my issues list; correctly
     lists issues without throwing an exception.
