cartridge app is failing to start after tt clean

[pavlua]

Environment: tt-ee 2.1.2, Tarantool EE 2.11

Steps to reproduce:

1. create and run default cartridge app:
   tt init
tt create cartridge --name app3
tt build app3
tt start app3
tt cartridge replicasets setup --bootstrap-vshard --name app3

2. run tt clean
   tt stop app3
cd app3 && tt clean

3. try to run app again
   cd .. && tt start app3

Expected result: app have been started, no errors in tarantool logs

Actual result: all of the tarantool instances have an error in logs
