[Bug] Does not respect DuckDuckGo settings for GET/POST requests

[ghost]

Describe the bug If you turn off GET requests in DuckDuckGo Privacy settings, the app will still use GET requests anyway instead of switching to POST. This can be verified by bookmarking a search result page and checking the bookmarked url.

How to Reproduce Steps to reproduce the behavior:

1. Do any search on DuckDuckGo
2. Scroll right through the headers at the top until you reach settings
3. Click "All Settings", then Privacy, and set GET requests to Off
4. Make other web searches and bookmark the URLs
5. Notice how the URLs contain the search request when they shouldn't

Expected behavior Switching off GET should use POST instead

Smartphone (please complete the following information):

• DDG App Version: 5.78.1
• Device: Nexus 5
• OS: Android 7.1.2
