Fix ICE when checking call overload

Browse source 
If the overloaded method does not have a tuple or unit type as its
first non-self parameter, produce a list of error types with the
correct length to prevent a later index bound panic.  This typically
occurs due to propagation of an earlier type error or unconstrained
type variable.  Closes #18532
