Mismatch between URL and internal state breaks back button behavior

**Affected Projects**

Web

**Library Version:** 3.0.0-rc19

Also whatever runs on https://opensource.appbase.io/reactivesearch/demos/gitxplore/

**Describe the bug**

There is a mismatch between the URL params and the component's internal state. The effect is that after applying a few filters, you can't set them to the previous value with the browser back button.

**To Reproduce**

Steps to reproduce the behavior:

1. Go to https://opensource.appbase.io/reactivesearch/demos/gitxplore/
2. Select Java and Ruby
3. Increase minimum stars to some value
4. Use browser back button (this should set minimum stars back to 0)
5. Use browser back button again, see that it doesn't do anything to the Java/Ruby selection

**Expected behavior**

Pressing back deselects the languages in reverse order in which they were added.
