session: delete and add application namespace do not create the global session table

When an application namespace is added, we call session_table_is_alloced
to see if we need to allocate a new session table. That check returns true
even if we removed the session table.
The fix is when we delete an application's global session table,
we need to invalidate fib_index_to_table_index.

Fixed test_vcl test script to run two tests back to back.
The 1st test deletes the application namespace at the end.
The 2nd test adds the application namespace in the beginning.

Type: fix
Fixes: 67bae20b05cb46e5f6d19afeaf1f7a52a5309d59
