Fix translation issue related to message showed on courseware progress

page related to certification and course mode. Part 2 of 2.

Use ugettext_lazy instead of ugettext to ensure the strings shown are in
the language the user chose. Otherwise the strings are in the platform
language.
Keep the original ugettext for function financial_assistance_form.
The test for that function fails if the text is not in english.
