* Fix a crash in the S/MIME configuration screen when a user turned off S/MIME,

     and then reenabled it. This crash was due to a double free of memory. To avoid
     this in the future, we created a function free_x509_store(), which whenever
     called, will only free memory once. A similar crash would occur when one
     attempted to enter the S/MIME configuration screen if S/MIME was turned off.
     In this case, Alpine would try to dereference a null pointer.
