Subject: [test/test_compat] Restore the old value of the HOME environment variable
X-Git-Url: http://git.bitcoin.ninja/index.cgi?p=youtube-dl;a=commitdiff_plain;h=f56875f2719868d191a51a1444720717c2e7e5c2

[test/test_compat] Restore the old value of the HOME environment variable

If the test was run before the YoutubeIE tests (for example by running
"nosetests -v test/test_compat.py test/test_download.py -m 'Youtube_1|compat_expand'"),
it wrote the signatures cache to the 'C:\Documents and Settings\тест\Application Data' folder.
It failed due to a problem in the cache code and the write_json_file function (fixed in f03e33b89a622af13fa5275c46b63aaa4814c499)
