[ML] Job wizards ignore kuery

[pheyos]

Found in version

• 7.0.0-alpha1 b2992

Browser

• Firefox

Steps to reproduce

• Activate the query language kuery in Kibana's advanced options
• Create a saved search using kuery specific syntax, i.e. not compatible with a standard lucene query (e.g. for the farequote dataset: airline: "ASA")
• Create a multi metric job based on that saved search

Expected result
Either:

• The datafeed handles the kuery query correctly

Or:

• An error is shown, explaining that kuery is not supported

Actual result

• The saved query is ignored and the datafeed runs with the default {"match_all":{"boost":1}} query

Additional information

• When using a lucene compatible query with kuery it works as expected (e.g. again for the farequote dataset the query airline: ASA works - note the missing quotation marks compared to the not working query above)
• In 6.4.1 b1806 this also happens with the difference that even lucene compatible kuery syntax is ignored
