ATM unconditional `resolvedStatus` call in `modality` causes a
performance degradation in our completion tests
Since `resolvedStatus` is called to make sure that all the
status-transforming compiler plugins had finished their job, it doesn't
make sense to call `resolvedStatus` if there are no such compiler
plugins registered
N.B. After KT-56551 is fixed, this optimization might become obsolete
and can be removed if proved so
