Fix finiteness check for bounded fmf (#3589)
Recently, finite model finding via uninterpreted sorts was decoupled from finite bound inference techniques (the BoundedIntegers module in theory/quantifiers/fmf/). This module assumed that finite model finding was enabled in one place. This fixes the issue by adding an additional check. This fixes a model unsoundness issue where bounds on an uninterpreted sort were not being enforced.
This fixes #3587.
