[PATCH v2] t6300: fix issues related to %(contents:size)

[Alban Gruin <alban.gruin@gmail.com>]

b6839fda68 (ref-filter: add support for %(contents:size), 2020-07-16)
added a new format for ref-filter, and added a function to generate
tests for this new feature in t6300.  Unfortunately, it tries to run
`test_expect_sucess' instead of `test_expect_success', and writes
$expect to `expected', but tries to read `expect'.  Those two issues
were probably unnoticed because the script only printed errors, but did
not crash.  This fixes these issues.
