Title: Fallback to allow both English or Empty language

When getting artworks, there is a 2 steps mechanism that 1st search
artwork of the prefered lang and if not found search for artwork in
english.
This change modifies the second step to allow both English('en') or
Empty('' or 'n/a' or None) language at the 2nd step.
