Reimport All" option of Context menu in Project View is broken in 2019.3 (in Asset Pipeline v2). Reproduced in 2019.3.0a3

How we can reproduce it:
- you need any "big" project (100-200 Mb) for testing it
Correct behavior:
1 when I open project in e.g. 2019.2.0b5 it imports my project for around 2 minutes, then in Project View I select "Reimport All" from Context menu and it reopens Unity Editor and imports project for the same (or almost the same) 2 minutes
Incorrect behavior:
2 when I open project in e.g. 2019.3.0a3(or any oher 2019.3 build up to a9 - latest for today) it imports my project for around 2 minutes, BUT then in Project View I select "Reimport All" from Context menu and it reopens Unity Editor and imports project for less than a minute

Actual results: 2019.3 uses Asset Pipeline v2 by default and "Reimport All" feature is broken there. That is regression!

Expected results: there are many changes in Asset Pipeline v2 and we need to decide if we need "Reimport All" feature at all. My opinion is that we still need to have it and so we need to fix it.
