[sr-dev] git:master:d72ac166: srdb1/schema: removed unique constraint from connection_idx

[Ovidiu Sas]

It's not this particular commit, but the previous one that created the index.
Even with <unique/> removed, the index seems to be unique on mysql.
Here's how the index was created:
CREATE INDEX connection_idx ON location (`server_id`, `connection_id`);
