54617: fix lookup in $commands array when hashlistall is unset

While the documentation for the zsh/parameter module does state
  The zsh/parameter module gives access to some of the internal hash tables
and
  commands
    This array gives access to the command hash table.
, the latter entry does *also* say
  values are the pathnames of the files that would be executed when
  the command would be invoked.

Change getpmcommand to always do a lookup via findcmd() if it the entry
is not found in the hash and HASHLISTALL is unset. This will indirectly
respect HASHCMDS and add the single entry if it is set, look it up in
the hash if it was added and then HASHCMDS was unset, etc.
