Accept `datasource` attribute on `DatasourceItem`, but ignore it

[amotl]

About

Dear @apepojken. This patch intends to poke at the details based on your report.

• GH-110

Details

When I try to explore datasources it always fail with a TypeError. No idea why this happens.

Exception:

TypeError: DatasourceItem.__init__() got an unexpected keyword argument 'datasource'

Thoughts

It is unlikely that this is the correct fix. It hasn't been validated in any way, so it is purely based on guessing, not even educated. We will ask a few more questions at GH-110.
