The EngineCache class replaces all previously individual solutions for caches in
the context of the engines.

For introspection of the DB, jump into developer environment and run command to
show cache state::

number of tables: 6
number of key/value pairs: 7
In the "cache tables and key/values" section, the table name (engine name) is at
first position on the second there is the calculated expire date and on the
third and fourth position the key/value is shown.
About duckduckgo: The *vqd coode* of ddg depends on the query term and therefore
the key is a hash value of the query term (to not to store the raw query term).
In the "properties of ENGINES_CACHE" section all properties of the SQLiteAppl /
ExpireCache and their last modification date are shown::

These properties provide information about the state of the ExpireCache and
control the behavior. For example, the maintenance intervals are controlled by
the last modification date of the LAST_MAINTENANCE property and the hash value
of the password can be used to detect whether the password has been changed (in
this case the DB entries can no longer be decrypted and the entire cache must be
discarded).

This patch fixes a bug reported by CI "Fetch traits" [1] (brave) and improves
other fetch traits functions (google, annas_archive & radio_browser).

Error: raise ValueError('%s missed a territory')

change ERROR message about unknow UI language to INFO message
radio_browser:
country_list contains duplicates that differ only in upper/lower case
annas_archive:
for better diff; sort the persistence of the traits

The use of img_src AND thumbnail in the default results makes no sense (only a
thumbnail is needed). In the current state this is rather confusing, because
img_src is displayed like a thumbnail (small) and thumbnail is displayed like an
image (large).
