Exit if error: describeTable with no parameters

[felipe88alves]

Fix: #1029
Backlog Item #183159888

Proposal is to add validation of the length of the arguments passed to the DescribeTable function prior to any validation of the arguments itself.

There were no tests on equivalent DescribeTable errors (i.e.: MultipleEntryBodyFunctionsForTable and InvalidEntryDescription). I don't know if there's any history there or not, but following convention, I also did not add tests for this new error. I'll gladly take comments on that decision.

No document updates were made since this simply reflects current expected behaviour.

thanks @felipe-alves-eric - yes these edges aren't particularly well-tested - but your approach here makes sense. a function with no inputs is invalid and this catches the issue identified in #1029 nicely.

Thanks for the feedback @onsi!
I really enjoyed contributing, would it be ok for me to continue taking tasks in the backlog to help out?
And if so, do you recommend any task to take?

hey @felipe88alves - sorry for missing this. Thanks for all the great work over on the MustPassRepeatedly decorator!

I'd love more help and if this flow of PRs/reviews is working for you we can think through a few other items.
