Fix spelling of words only misspelled in tests, part 2

Problem/Motivation

Fix spelling of words only misspelled in tests, part 2

I found these words by applying #3379121: Skip spellcheck for 17 nonsense words that are parts of hashes and #3328741: Add a dictionary for Drupal specific words and then searching core test for the words in the dictionary where the word is used in a variable name. And also avoided the more challenging words, like the one that have a 'able' suffix or an 'un prefix.

Steps to reproduce

Proposed resolution

Correct spelling for these words and remove word from dictionary.
