[PATCH v1 6/8] t4014: fix tests overwriting cover letter in silent

[Firmin Martin <firminmartin24@gmail.com>]

These tests are broken due to the new configuration option
format.confirmOvewrite whose the default value requires confirmation
from user whenever an existing cover letter is subject to be
overwritten.

Also change some pairs of git config and git config --unset to a single
test_config.
