SSR fails with sortOptions in ReactiveList

[multidis]

Issue Type: bug

Platform: Web

Description:
When sortOptions prop is passed to ReactiveList it fails with server-side rendering. The error traces to "only used for SSR" - commented code block here.

Uncaught (in promise) TypeError: Cannot read property 'sortOptionIndex' of undefined

options.sort = [(_ref10 = {}, _ref10[props.sortOptions[undefined.sortOptionIndex].dataField] =

Screenshots:

Minimal reproduction of the problem with instructions:

Working example without sortOptions prop (master-branch):

Failing example with sortOptions prop: switch to the sorting branch where an array or sorting options was added

Reactivesearch version: 3.0.0-rc.15

Browser: [all | Chrome XX | Firefox XX | Edge XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

Anything else:

This example is based on the following issue originally resolved with reactivesearch v2:
