Regression introduced in "Views reference results in 414 if many options set and ajax used"

Problem/Motivation

Unfortunately I introduced a regression in #3396530: Views reference results in 414 if many options set and ajax used. The test coverage is not actually having an override in place view a views setting plugin and as a result missed this.

Steps to reproduce

Attempt to override e.g. page limit. Default a view to 5 per page, enable the limit setting, and set to e.g. 2 per page. Only the first page has 2, subsequent ajax loads revert to 5.

Proposed resolution

Fix the regression
Add better test coverage
