[PATCH v2] t3900: do not reference numbered arguments from the test script

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <j6t@kdbg.org>

The call to test_expect_success is nested inside a function, whose
arguments the test code wants to access. But it is not specified that any
unexpanded $1, $2, $3, etc in the test code will access the surrounding
function's arguments. Rather, they will access the arguments of the
function that happens to eval the test code.

In this case, the reference is intended to supply '-m message' to a call of
'git commit --squash'. Remove it because -m is optional and the test case
does not check for it. There are tests in t7500 that check combinations of
--squash and -m.

Yes, it's broken and this patch just removes the reference.
