Unsurprisingly, this fixes the breakage for me.
I used the attached patch to keep t9300 running when the breakage
was detected.

Subject: [PATCH] t9300-fast-import: avoid 'exit' in test_expect_success snippets
Exiting from a for-loop early using '|| break' does not propagate the
failure code, and for this reason, the tests used just 'exit'. But this
ends the test script with 'FATAL: Unexpected exit code 1' in the case of
a failed test.
Fix this by moving the loop into a shell function, from which we can
simply return early.
While at it, modernize the style of the affected test cases.
