Empty string sentence in cv-corpus-5-2020-06-22/en/test.tsv

While processing entries from cv-corpus-5-2020-06-22/en/test.tsv, I have discovered an empty string sentence on line #557 referencing common_voice_en_16759015.mp3. I haven’t checked the remaining entries to see if there are more of such cases.

Is this a real issue or am I seeing this not correctly?

I have filed a bug related with CorporaCreator to this issue: https://github.com/mozilla/CorporaCreator/issues/108. Please see discussion thread there.
