Error on inserting null value for MVA field in Elastic-like bulk request

[Nick-S-2018]

Bug Description:

Daemon returns an error in the following case:

curl localhost:9408/cli -d 'create table test(f multi)'

curl localhost:9408/_bulk -H "Content-Type: application/x-ndjson"  -d '
{"index":{"_index":"test"}}
{"f":null}
'
{"error":"row 1, column 1: non-MVA value specified for a MVA column"}

Instead of raising the error, we must convert null to the default value for the MVA field.
