tag: respect color.ui config

Since 11b087adfd (ref-filter: consult want_color() before emitting colors, 2017-07-13), we expect that setting "color.ui" to "always" will enable color tag formats even without a tty. As that commit was built on top of 136c8c8b8f (color: check color.ui in git_default_config(), 2017-07-13) from the same series, we didn't need to touch tag's config parsing at all. However, since we reverted 136c8c8b8f, we now need to explicitly call git_color_default_config() to make this work. Let's do so, and also restore the test dropped in 0c88bf5050 (provide --color option for all ref-filter users, 2017-10-03). That commit swapped out our "color.ui=always" test for "--color" in preparation for "always" going away. But since it is here to stay, we should test both cases. Note that for-each-ref also lost its color.ui support as part of reverting 136c8c8b8f. But as a plumbing command, it should _not_ respect the color.ui config. Since it also gained a --color option in 0c88bf5050, that's the correct way to ask it for color. We'll continue to test that, and confirm that "color.ui" is not respected.
