Remove old slapproxy tables when migrating to new version
Some tools are using directly slapproxy sqlite database and they stopped working when table number was increased in !76 (merged) .
We made a quick improvement to the tools so that they can autodetect the current table names instead of hardcoding ( slapos@b8c895cd ) but this failed, because slapproxy remove did not remove the old tables after migration. This branch is about removing the table, to quickly repair these tools.
The long term plan is (hopefully) to improve these tools so that they don't use the private tables like this.
