Swatch Text attributes options not created correctly via api

[jakubderdziak]

Preconditions

1. Magento 2.2.5
2. PHP7.1

Steps to reproduce

1. Create a select attribute
2. Make this attribute text swatch
3. Try adding attribute options through the API via POST /V1/products/attributes/{attributeCode}/options
4. See attribute in admin panel

Expected result

The attribute option should have "Swatch" and "Description" set
After adding two options, I can save attribute

Actual result

Only "Description" is filled
After adding two options that way, unable to save attribute

Note

The other way to reproduce it is to add option via php, the same way as in: #11032
