reset: do not make '--quiet' disable index refresh
Update '--quiet' to no longer implicitly skip refreshing the index in a
mixed reset. Users now have the ability to explicitly disable refreshing the
index with the '--no-refresh' option, so they no longer need to use
'--quiet' to do so. Moreover, we explicitly remove the refresh-skipping
behavior from '--quiet' because it is completely unrelated to the stated
purpose of the option: "Be quiet, only report errors."
