[evgenybf]

Describe the bug
After returning to a page with configured Filter parameters, records are not filtered until the parameters are changed again.

To Reproduce

1. Go to the demo site, to the "Blog Posts" view: https://starlette-admin-demo.jowilf.com/admin/sqla/post/list

2. Select Filter, "Title, Contains, test"
   
   Result: Filter is applied, records are filtered. - correct.

3. Go to another view, e.g. "Comments", get back to "Blog Posts".
   Result: Filter is set, but records are not filtered - wrong.
   

Environment (please complete the following information):

• starlette_admin~=0.14.1
• ORM/ODMs: [SQLAlchemy, MongoEngine]
  also can be reproduced on the official demo site.

(it's a different bug, but has some similarities)

Field search filter behaves weirdly:

1. when model.save_state=True
   Add search value, refresh the page - search string keeps the search value, filter is applied - OK
   Revisit the page. Search value is empty, filter is still applied. - wrong
   

2. when model.save_state=False
   Add search value, refresh the page - search string keeps the search value, filter is not applied. - OK?
   Revisit the page. Search value is empty, filter is not applied. - OK

I think we need a deep work on the state management and consider saving the state in the URL. All of this is possible with DataTables

when model.save_state=False
Add search value, refresh the page - search string keeps the search value, filter is not applied. - OK?
Revisit the page. Search value is empty, filter is not applied. - OK

By default datatables keep the state for 2hour https://datatables.net/examples/basic_init/state_save.html
