Bug 23991: Move SearchSuggestion to Koha::Suggestions

Bug 23991: Move SearchSuggestion to Koha::Suggestions

The C4::Suggestions::SearchSuggestion subroutine is badly written and
can be replaced by calls to Koha::Suggestions->search.
The hard part in this patch is suggestion.pl, the other occurrences have
been replaced easily.

Test plan:
The idea is to test the whole suggestion workflow.
1. Create a suggestion on OPAC
2. Create a suggestion on the staff interface
3. Edit suggestions
4. Filter suggestions (use the different filters and "organize by"
values)

Bug 23991: (QA follow-up) Save some DB queries

This patch makes the suggestion-related pages rely on array size instead
of querying the DB each time they need to. In the case of
suggestion/suggestion.pl it goes from 4 COUNT(*) to 1.

To test, with KTD:
1. Run on the host machine:
    $ docker exec -ti koha_db_1 bash
    $ mysql -ppassword
    > SET GLOBAL general_log_file='/var/log/mysql/mycustom.log';
    > SET GLOBAL log_output = 'FILE';
    > SET GLOBAL general_log = 'ON';
    > \q
    $ tail -f /var/log/mysql/mycustom.log | grep suggestions
2. Visit the different pages changed on this bug
=> SUCCESS: Some queries
3. Apply this patch
4. Repeat 2
=> SUCCESS: Less queries!
5. Sign off :-D
