Fix kwarg expectations with new rspec fixes, eg,

  1) ThinkingSphinx.count passes through the given query and options
     Failure/Error:
       expect(ThinkingSphinx::Search).to receive(:new).with('foo', :bar => :baz).
         and_return(search)

     ArgumentError:
       wrong number of arguments (given 1, expected 0)

Fix a LogSubscriber deprecation in Rails 7.1 prevents this deprecation warning:

DEPRECATION WARNING: Bolding log text with a positional boolean is deprecated and will be removed in Rails 7.2. Use an option hash instead (eg. `color("my text", :red, bold: true)`).
