CNDB-16135: reuse table directory from Directories into Descriptor (#2150)

### What is the issue
CNDB-16135: Descriptor uses different instances of `Path directory` for
the same table as constructor parameter

### What does this PR fix and why was it fixed

Use the table directory from `Directories` in `Descriptor` as
constructor parameter . `Descriptor#directory` is still different
instance in C* due to `directory#toCanonical()` which always creates new
instance in local file system
