Adding exception when calculating default distro
Currently the jobs that downloads the isos are failing at:
Traceback (most recent call last):
File "/usr/bin/download-latest-test-iso", line 35, in <module>
DEFAULT_RELEASE = distro_info.UbuntuDistroInfo().devel()
File "/usr/lib/python2.7/dist-packages/distro_info.py", line 96, in devel
raise DistroDataOutdated()
distro_info.DistroDataOutdated: Distribution data outdated. Please check for
an update for distro-info-data. See
/usr/share/doc/distro-info-data/README.Debian for details.
I added an exception so when it raises, the default variable is assigned and
the script continues.
