[PATCH 2/4] Revert "t6006: drop "always" color config tests"

[Jeff King]

This reverts commit c5bdfe677cfab5b2e87771c35565d44d3198efda.

That commit was done primarily to prepare for the weakening
of "always" in 6be4595edb (color: make "always" the same as
"auto" in config, 2017-10-03). But since we've now reverted
6be4595edb, there's no need for us to remove "-c
color.ui=always" from the tests. And in fact it's a good
idea to restore these tests, to make sure that "always"
continues to work.
