Lucene index with 0 posts incorrect

[Stephan Doerfel]

Lucene index is show to be incorrect (and with a weird date) when an index is tried to be created with 0 posts (e.g. when a system has no goldstandard posts).

Currently the Index#isCorrect functions return false if the number of posts is equal to 0 before it queries the database with an evil count. I think we should keep it because the count query is executed on the main database.
