Issues installing wikidata_linker_utils_src with Cython 0.28

[lucolivi]

I had issues installing wikidata_linker_utils_src with Cython 0.28 (as per allowed by the requirements).

Rolling back to 0.26 worked fine.

I have save problems when run "python3 setup.py build" for wikidata_linker_utils_src

some like this: successor_mask.pyx:1046:38: Unicode literals do not support coercion to C types other than Py_UNICODE/Py_UCS4 (for characters) or Py_UNICODE* (for strings).

last one like this: successor_mask.pyx:1054:34: ambiguous overloaded method
