When setting a report with a `report_name` without dots,
the associated views button raised an exception.
This has been introduced during the migration to the new API
at revision 47c67b640b
Before, a try/except made sure the exception to not raise
the exception in case the report name could not be split
in two parts.
In this revision, instead of doing the try/except,
we check if the result of the split has a minimum
length of 2.
