BUG: GraphQL proxy incorrectly converts dates to invalid format

Webix JS
#1

When serializing dates to send in GraphQL queries, they should be converted to the ISO8601 format, YYYY-MM-DDTHH:MM:SSZ. Instead, Webix converts them to a non-standard format,
YYYY-MM-DD HH:MM.

This won’t work with compliant GraphQL servers (see my sample) using DateTime libraries like graphql-iso-date.
