Problem in migration e2e tests

• when a site is created in v0.9.0 and without any wait you try to perform curl operation it returns 5XX status code, but after some time it returns 2xx
  Status: Fixed
  Fix: Updated the curl command with retry flag

• when a site is running in v0.9.0 and migrated to latest version there is problem deleting the site becuase there is some migration setup where the folder perm changed to 1000 uid,guid and thus removing access to the folder for the site from the current user
  Status: Fixed
  Fix: Updated the removeal of ~/frappe dir with sudo
