Re: [PATCH 2/7] tests: fix a memory leak in test-parse-options.c

In c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09)
the "list" variable was added, and later on in
c8ba1639165 (parse-options: add OPT_STRING_LIST helper, 2011-06-09)
the "expect" was added.

The "list" variable was last touched in 2721ce21e43 (use string_list
initializer consistently, 2016-06-13), but it was still left at the
static scope, it's better to move it to the function for consistency.
