[SR-Users] mongodb and jansson

[Daniel-Constantin Mierla]

Hello,

thanks for investigating and providing the patch.

Can you make a pull request on github? The patch is small but can be
merged from small devices while traveling and also ensures that it
compiles on TravisCI (without a need to compile locally).

Cheers,
Daniel
