test(eliza): Fix keyword ranking test to match Python solution behavior

When both "i" and "always" keywords have no explicit rank (default 0),
the keyword that appears first in the input should be matched first.
This matches Python's stable sort behavior in the original solution.

Changed test expectation from "always" to "i" for input "i always do that"
since "i" appears before "always" in the sentence.
