system_SUITE: Work around file provider issue in `list` testcase 

The file provider uses stat(2) which has a resolution of one second in
Erlang. Thus, the refresh may miss the new test certificates if the
creation happens in the same second after the previous refresh.

References #58.

%% FIXME: The file provider calls stat(2) on the certificate
%% directory to detect any new certificates. Unfortunately, the
%% modification time has a resolution of one second. Thus, it can
%% miss certificates added within the same second after a refresh.
%% To workaround this, we force a refresh, wait for two seconds,
%% write the test certificate and call refresh again.

%% Once this is fixed, the two lines below can be removed.
