PYCBC-1694: Allow setting min=0 in DisjunctionQuery

Motivation
==========
The server accepts disjunction queries with min=0. In the case of a standalone DisjunctionQuery, it is equivalent to the default (min=1). When used as part of a BooleanQuery, min=0 means that the disjuncts only affect the scoring.

Change
======
Update DisjunctionQuery.min setter to only raise an error if min is negative.

Results
=======
Relevant FIT test passes (SearchTest.booleanQueryNotMatchMin0)
