[PATCH v2 1/2] Revert "test-lib.sh: do tests for color support after changing HOME"

[Richard Hansen <rhansen@xxxxxxx>]

This reverts commit 102fc80d32094ad6598b17ab9d607516ee8edc4a.

There are two issues with that commit:

  * It is buggy.  In pseudocode, it is doing:

       color is set || TERM != dumb && color works && color=t

    when it should be doing:

       color is set || { TERM != dumb && color works && color=t }

  * It unnecessarily disables color when tput needs to read
    ~/.terminfo to get the control sequences.
