Bug 11503: [Follow-up] fix another typo

There is still a typo left to fix which I didn't catch because I was
doing a spell-check and didn't double-check the bug report:

Van der Griten -> Van der Grinten

Bug 11509: (trivial rmaint followup) wrong parameter count

While adding the --help and -h switches I forgot to change to arguments
count validation so that one can actually use those parameters (i.e.
koha-create should accept being invoked with only one parameter).

This patch just changes the minimum parateres required from 2 to 1.

To reproduce:
- Run 'koha-create --help' from master
=> Usage information is printed BUT ALSO an "Error: wrong parameters"
   message
- Apply the patch and
- Run 'koha-create --help'
=> Usage informatio it printed and no error message.
