If we try to put malformed data into an integer field, Elasticsearch
rejects the whole document.
Setting 'ignore_malformed' to true allows to ignore malformed data and
process the other fields of the document normally

Test plan:
* Without the patch
1. In search engine configuration, change the type of a text field to
'Number' (for instance 'title')
2. misc/search_tools/rebuild_elasticsearch.pl -d -b
3. See that the index is empty (unless you have titles consisting only
of digits)
* With the patch
1. misc/search_tools/rebuild_elasticsearch.pl -d -b
2. Now records are correctly indexed
