Bug on Topic create form
**Describe the bug**
We need to fix loader on Topic page. After success topic creation the first time, we won't wait for creation any more, because state is loaded, and we will try to get entity immediately after pressing the button, and we will receive null
going to object page on the second creation. 

**Steps to Reproduce**
1. Create topic 1 
2. Create topic 2

**Expected behavior**
Topic form should work without FetchStatus reducer


**AC:**
- Topic new form works without fetchStatus reducer and tracks async request status using react-hook-form 
- Topic new form covered by tests.
