There is no way to create report for multiple objects

[Egor Tsinko]

When attempting to create a report for multiple objects an error is thrown. I.e.:

oerp.report('report_name', 'report_model', [id1, id2, id3]) causes an error,

 while separate calls are ok:

oerp.report('report_name', 'report_model', id1)
oerp.report('report_name', 'report_model', id2)
oerp.report('report_name', 'report_model', id3)
