* src/hsts.c (hsts_store_merge): call hsts_new_entry() if the entry
does not exist in the database.
When merging the existing HSTS database on disk with the one on memory,
the entries that were on disk but not on memory were ignored. Thus,
only the existing entries were merged. This behavior was only triggered
when more than one Wget processes were using the same HSTS database
simultaneously. This commit fixes the bug by adding the new entries
to the on-memory database if they were not found there.
