Using mastertickets plugin with already existants tickets cause error
|Reported by:||nextime||Owned by:||coderanger|
When you try to view an old ticket, created before to install the plugin, the ticket_custom table
don't have the relative ticket_custom.name = 'blocking' entry, so, in line 56 of the web_ui.py
of mastertickets you get an error cause it try to do a replace on a None value for block_ids.
A simple patch that move the line 56 after the if blocks_ids: line (57) fix this issue.
