(maint) Catch perm error in replication set update
(maint) Catch perm error in replication set update

Changes exception behavior of update-pglogical-replication-set. If the
db user don't have rights to update pglogical, catches the exception and
returns false. Other exceptions are passed through.

This fixes db migration crashes in users of this function when pglogical
is installed but the database is read-only.
