mappings: index call_numbers as text

* Fixes inconsistent mapping between documents and items/holdings for
call numbers.
* Closes #2908.

:warning: Requires ES update mapping!
:warning: Requires reindexing of `call_number` and `second_call_number`
for all items and holdings, as well as `inherited_first_call_number` for
items of type `issue`.
