Fix es translations

There's a problem in the Spanish translations where they are invalid
and cannot get compiled.

We're not syncing with translation server anymore, so update the strings
manually and fix them.

To verify run
find nova -type f -regex '.*\.pot?' -print0| xargs -0 -n 1 msgfmt \
--check-format -o /dev/null

Before this change:
nova/locale/es/LC_MESSAGES/nova.po:5557: 'msgstr' is not a valid Python
format string, unlike 'msgid'. Reason: The string ends in the middle of
a directive.
nova/locale/es/LC_MESSAGES/nova.po:5567: 'msgstr' is not a valid Python
format string, unlike 'msgid'. Reason: The string ends in the middle of
a directive.
msgfmt: found 2 fatal errors
nova/locale/es/LC_MESSAGES/nova-log-error.po:1366: a format
specification for argument 'args' doesn't exist in 'msgstr'
msgfmt: found 1 fatal error

Now this works fine.
