standby clone: fixes for Barman tablespace handling.

Browse Source 
repmgr creates a file with a list of tablespace files to fetch from
Barman, however the file may not actually have been flushed to disk
at the point the rsync operation was executed, so may be incomplete
or empty.

Also fix handling of tablespace remapping.

Addresses GitHub #650.
