fix(common): parameter name is not derived from parameter type (#4908)

Right not we use case sensitive comparison when trying to determine the parameter name. Apparently, parameter name normally starts with lower case, and parameter type name starts with upper case. That means in some cases like the parameter type has been renamed by using [CodeGenModel], case sensitive comparison doesn't work and that will generate incorrect parameter name.
