As requested by RM, this patch replaces using the global $cached_indicators
by saving state temporarily during the (limited) lifetime of the object.
Essentially this affects two places in code:
[1] blinddetail-biblio-search.pl (loading auth record in editor)
[2] AuthoritiesMarc::merge (merging authority into biblios)
Concurrent runs of [1] and/or [2] together with a simultaneous pref change
just in between could cause slight (hypothetical) side-effects.
The current approach of keeping state in the object makes that a series of
controlled_indicators calls during an immediate merge of one specific
authority is not affected by a simultaneous pref change. So the same rules
are applied to the set of attached biblio record for that authority.
Note also that the cron job ignores a simultaneous pref change, since
it reads from the unchanged L1 cache (yes, also hypothetical).
Test plan:
[1] Run t/Koha/Authority/ControlledIndicators.t
[2] Run t/db_dependent/Authority/Merge.t
[3] Run t/db_dependent/Koha/Authorities.t
