BUG-5055: Initialization of LocRib Table

When LocRib table are created when insert already
existan routes. They where created when inserting
supported tables. Which will make the process to be
repeated if more than one table is supported.
Solved by move the process at the point where
specific table is created.
Also fixed onTable change, since it should add only
table to corresponding LocribWriter listener
