Fix RexOps#1508 simply by correcting typo on a couple lines

Notice that how params and args were mixed up (interchanged)
when being passed down  -- within the needs() function.

This appears to be a typo, introduced initially
by PR RexOps#1157 (the fix for RexOps#1066 ) with 48c737b.

CHANGES:
=============
modified: lib/Rex/Command.pm

HOW TO TEST :
=============

$ prove -v t/issue/1508.t   # for this issue
$ prove t/**/*.t            # for non-regression

While the related tests remain marked as "TODO",
they will not report failures during normal test runs.

To see their true pass/fail status, you have to pass
the '-v' option to `prove`.
