Query DSL: don't change state of the bool query while converting to lucene query 

We used to change the minimumShouldMatch field of the query depending on the context, the final minimim should match should still be applied based on that, but the original minimumShouldMatch of the query shouldn't change. This was revelead by some recent test failure.

Closes #14153
