  lib-storage: Fix memory leak in mail_search_args_simplify()

The leaks happened when search args were already initialized (which they
usually were at this point) and some of the args were dropped entirely.

Improved the unit test to initialize search args before calling the
simplify, so valgrind would notice if there are any leaks.
