Catalog rule contains-condition not saving multiple selection in 2.1.2

[mveldhuizen]

Preconditions

1. Magento version 2.1.2
2. Installed default sample data

Steps to reproduce

1. Add new catalog price rule
2. General information doesn't seem to matter
3. Add contains-condition with multiple options
4. Example: Climate contains Spring, Warm
5. Save the rule

Expected result

1. POST should contain both values for example:
   rule[conditions][1--1][type]:Magento\CatalogRule\Model\Rule\Condition\Product rule[conditions][1--1][attribute]:climate rule[conditions][1--1][operator]:{} rule[conditions][1--1][value][]:208 rule[conditions][1--1][value][]:209
2. Rule should be saved and condition should state: Climate contains Spring, Warm
   

Actual result

1. POST contains only first selected value
   rule[conditions][1--1][type]:Magento\CatalogRule\Model\Rule\Condition\Product rule[conditions][1--1][attribute]:climate rule[conditions][1--1][operator]:{} rule[conditions][1--1][value][]:208
2. Rule is saved and condition is: Climate contains Spring

I can confirm this is happening in 2.1.3 as well. I tested on 2 different installations.

I've managed to find and create a fix for the issue. It is now waiting for magento team approval in pull request. If you need quicker solution you can use a module with the fix I prepared at my company:

@Zefiryn will this also fix the issue of using multiple sku's? I.e. SKU "is one of" [sku], [sku]. #8215 That issue seems related. If this fixes it, it would be awesome.
