t4202: use test_config/test_unconfig to set/unset git config variables

Instead of using construct such as:
    test_when_finished "git config --unset <key>"
    git config <key> <value>
uses
    test_config <key> <value>
The latter takes care of removing <key> at the end of the test.

Additionally, instead of
     git config <key> ""
or
     git config --unset <key>
uses
     test_unconfig <key>
The latter doesn't failed if <key> is not defined.

Tests are modified to assume correct (default) configuration at entry,
and to reset the modified configuration variables at the end.
