Fixed few more UI failures

Fixed: `test_negative_create_{0-2}` org test by setting the edit variable value to False
Fixed: `org`, `location`, `domain`, `config_group`, `medium` tests by placing wait_for_ajax before calling search fn
Fixed: `test_negative_create{1-4}` location tests

This PR will fix almost all org and location tests. Also, some tests were failing while asserting final result via search. I think its because now navigation is part of search function. So after each `go_to` statement we need to add wait_for_ajax. I hope this PR should fix bunch of more tests.

Also, this PR needs to be cherry-picked to master. I'll do that once it will be merged. thanks
