Auto merge of #358 - sru:test-multiple-values, r=Vinatorul
tests(multiple_values): move tests related to multiple values #166. Currently, there are four different error types that indicate the same thing: `TooManyArgs`, `TooManyValues`, `TooFewValues`, `WrongNumValues`. I wasn't sure which error they give. Therefore, I just checked that it gives error, but I do not check which error it gives.
