Check param count only, not param order correctness

This change simplifies client 'createpaymentacct' method parameter
validation.  It no longer assumes parameter ordering is correct, and
only verifies the string parameter count is correct.

A unit test was also added to cli/test.sh

This commit is in response to the requested change in PR 4308.
