i18n: rake gettext:find would fail in certain scenarios

[mzazrivec]

In certain scenarios, for example when config/locales/manageiq.pot file doesn't exist,
gettext:find rake task would fail with the following:

$ bundle exec rake --trace gettext:find
...
** Execute config/locales/manageiq.pot
#<GetText::RubyLexX:0x0056521622efe8>#<GetText::RubyLexX:0x0056521622efe8>** Invoke config/locales/nl (first_time, not_needed)
** Invoke gettext:internal:force (first_time)
** Execute gettext:internal:force
rake aborted!
