API: error message missing variable

[romuald]

Using an invalid value as the limit parameter will raise an error with an invalid message:

% curl http://baobab.local/api/events'?limit=20truc'

Invalid limit '%s' provided. Please provide a positive integer.

But should be Invalid limit '20truc' provided. Please provide a positive integer.

This has been fix upstream see commit
We used tastypie version 0.9.10 to have the fix we need at least 0.9.12
We could create our own paginator to fixed it but I don't think it's worth it.
